Abstract
Polyene cyclization has emerged as a powerful tool for increasing molecular complexity. In recent years, gold-catalyzed polyene cyclization reactions have made significant progress, particularly in the total synthesis of complex polycyclic natural products with biological activity. Simultaneously constructing multiple stereogenic centers and core polycyclic ring structures, especially through the catalytic asymmetric reactions, greatly improves the efficiency of natural product synthesis. The alkynyl functional group can initiate polyene cyclization reactions, and the resulting vinyl moiety can facilitate subsequent functional group transformations, making it highly versatile. This review mainly summarizes the synthetic methodology of polyene cyclization reactions based on the underlying mechanisms and their applications in the total synthesis of polycyclic natural products.

Abstract
In the era of global warming, the conversion of carbon dioxide into high-value products has become a widely scrutinized emerging mitigation strategy. Metalation of bpy-containing MOF-253 led to the synthesis of MOF-253-0.5Ag, which acts as an efficient catalyst for the carbonylative cyclization of CO2 with alkyne molecules (such as propynyl alcohols and propynyl amines) at room temperature and ambient CO2 pressure, yielding the corresponding α-alkyl cyclic carbonates and oxazolidinones, thus endowing the catalytic system with bifunctional characteristics. Additionally, the MOF-253-0.5Ag catalyst demonstrated stability, high activity, and recyclability. The mechanisms were further elucidated through experimental results and NMR analysis, demonstrating that Ag(I) can effectively activate the C≡C bonds and hydroxy/amino groups of the substrates.

Abstract
[Au]-catalyzed and substrate-dependent intramolecular cyclization of sulfonyl ene-amides with a pendant propargyl group afford tetrasubstituted pyrroles, o-aminophenols, or 1,6-dihydropyridine carbaldehydes. While the pyrroles and aminophenols are formed when the propargylic alkyne is terminal, dihydropyridines are formed when internal alkyne is present. Internal alkyne substrates with 2-thienyl and 3-thienyl groups give different types of dihydropyridines. The dihydropyridines so obtained can be readily converted to nicotinaldehydes with concomitant sulfonyl migration upon heating in xylene.

Abstract
A wide variety of regioselectively substituted carbazole derivatives can be synthesized by the gold-catalyzed cyclization of alkynols bearing an indol-3-yl and an additional group at the homopropargylic positions. The regioselectivity of the process can be controlled by both the oxidation state of the gold catalyst and the electronic nature of the substituents of the alkynol moiety. The 1,2-alkyl migration in the spiroindoleninium intermediate, generated after indole attack to the activated alkyne, is favored with gold(I) complexes and for electron-rich aromatic substituents at the homopropargylic position, whereas the 1,2-alkenyl shift is preferred when using gold(III) salts and for alkyl or non-electron-rich aromatic groups.

Abstract
A new mechanistic pathway of propargylic alcohol activation by gold(I) catalysis has been proposed toward the efficient synthesis of N-protected pyrroles, 5,6-dihydropyridin-3(4H)-ones from N-protected 5-aminopent-2-yn-1-ol, and 5-aminopent-2-yn-1-ol. Control experiments support that the reaction proceeded via the neighboring group participation of the oxygen atom of propargylic alcohol to form an allene oxide intermediate where the nucleophilic heteroatom attacks intramolecularly. Further, this methodology is successfully extrapolated toward the atom-economic synthesis of hydroxyalkyl indoles and benzofurans. The short reaction time of 30 s, low catalyst loading of 0.5 mol %, high yield, variation in the substrate scope, and procedurally simple open-flask reaction conditions make this methodology highly applied.

Abstract
An alkyl intercepted Meyer-Schuster rearrangement reaction with α,β-unsaturated ketones as the electrophiles was first investigated, which provided a facile method to construct 2-methylene-pentane-1,5-diones. Then the in situ generated 2-methylene-pentane-1,5-diones underwent a Michael addition to give diverse 2-malononitrile methyl substituted pentane-1,5-diones in a one-pot fashion. This transformation was reliable on a gram scale. The high yield, convenient experimental operation, and 100% atom economy made it a valuable method for the construction of 1,2,3,5-tetrasubstituted pentane-1,5-dione derivatives.

Abstract
A new Brønsted acid-catalyzed oxo-cyclization of propargyl alcohols with azlactones to synthesize C2-azlactonized 2H-chromenes has been established that uses 1,1'-binaphthyl-2,2'-diyl hydrogen phosphate (BiNPO4H) as the catalyst and gives excellent diastereoselectivities (≥19:1 dr) in most cases. This protocol has a high compatibility with various substituents of substrates, offering a catalytic and useful entry to the fabrication of the synthetically important C2-functionalized 2H-chromene scaffold.

Abstract
Design and synthesis of a new class of γ-butenolides, viz. β-aryl-γ-propenylidene-γ-butenolides, have been reported from β-aryl-Z-enoate propargylic alcohols in the presence of acid. Isolation of β-aryl-γ-propenylidene-γ-butenolides and their O18-isomer confirmed the intermediacy of the allenyl-lactonium ion as well as the cyclic-hemiacetal during the proposed mechanism. By utilizing the β-aryl-γ-methylenecyclohexenylidene-γ-butenolides as starting materials, a highly stereoselective and efficient approach has been developed for the syntheses of frameworks of rubrolide natural products. This strategy was further extended for the total synthesis of rubrolide E.

Abstract
Stabilized by a bulky N-heterocyclic carbene [BP DPr, 1,3-bis(2,6-diisopropylphenyl)-1,3-diazonine-2-ylidene] ligand, new silver carboxylate complexes of the form BP DPrAgO2 C-R (R=Me, Ph) have been synthesized and fully characterized in solution and in the solid state and implemented as sole catalysts (base-, additive-, and, in some cases, solvent-free) in the challenging fixation of carbon dioxide to unsubstituted propargylic derivatives for the synthesis of oxazolidinones and α-methylene cyclic carbonates. Derived from X-ray diffraction studies, the molecular geometry and the concept of buried volume were employed to describe the structural and steric features of these silver complexes. Their stability and efficiency as catalysts have been demonstrated by the synthesis of 29 carboxylation products (72-98 % yield) at low catalyst loadings (0.01-1.5 mol%). Characteristics are high turnover numbers (up to 9400), catalyst recyclability (up to 96 % yield after the 7th cycle with no decomposition of the silver complex), and the possibility to scale-up the reaction.

Abstract
Heteroarene-tethered functionalized alkynes are multipotent synthons in organic chemistry. This detailed Review described herein offers a thorough discussion of the metamorphosis of heteroarene-tethered functionalized alkynes, an area which has earned much attention over the past decade in the straightforward synthesis of architecturally complex heterocyclic scaffolds in atom and step economic manner. Depending upon the variety of functionalized alkynes, this Review is divided into multiple sections. Amongst the vast array of synthetic transformations covered, dearomatizing spirocyclizations and cascade spirocyclization/rearrangement are of great interest. Synthetic transformations involving the heteroarene-tethered functionalized alkynes with scope, challenges, limitations, mechanism, their application in the total synthesis of natural products and future perceptions are surveyed.

Abstract
Three- and four-membered rings, widespread motifs in nature and medicinal chemistry, have fascinated chemists ever since their discovery. However, due to energetic considerations, small rings are often difficult to assemble. In this regard, homogeneous gold catalysis has emerged as a powerful tool to construct these highly strained carbocycles. This review aims to provide a comprehensive summary of all the major advances and discoveries made in the gold-catalyzed synthesis of cyclopropanes, cyclopropenes, cyclobutanes, cyclobutenes, and their corresponding heterocyclic or heterosubstituted analogs.

Abstract
The C-O bond cleavage of a propargylic alcohol, 1,1-dimethyl-3-phenylprop-2-yn-1-ol (3), by metal-ligand cooperation was investigated. The reactions of a naphthalene complex [CpRu(η6-C10H8)]PF6 (Cp = η5-C5H5) with 5-R-3-(pyrid-2-yl)pyrazoles (R-LH; R = Ph, CF3) in acetonitrile afforded the starting metal-ligand bifunctional ruthenium complexes [CpRu(R-LH)(MeCN)]PF6 (1a, R = Ph; 1b, R = CF3) featuring an N-N chelate protic pyrazole. The treatment of the CF3-substituted pyrazole complex 1b with 3 in 1,2-dichloroethane at 50 °C resulted in the formation of the η3-butadienyl complex 5. Meanwhile, the corresponding reaction of the phenylpyrazole complex 1a in 1,4-dioxane at 90 °C gave the N-allenylmethylpyrazole complex 6. The C-O and C-H bond cleavage of 3 in these reactions can be ascribed to the metal-ligand cooperation: initial formation of an η3-propargyl complex assisted by NHO hydrogen bonding and following C-H deprotonation by the neighboring pyrazolato ligand. On the other hand, in boiling methanol, the protic pyrazole complex 1a catalyzed the C-O bond cleavage of 3, which resulted in catalytic isomerization of 3 to an α,β-unsaturated enone, 3-methyl-1-phenylbut-2-en-1-one (8). The control experiments using non-protic and isocyanide ruthenium complexes indicated that both a labile nitrile ligand on the metal and the protic cooperating ligand are crucial for the catalysis.

Abstract
A novel and selective cascade reaction of primary amines and alkynes for the synthesis of the corresponding secondary propargylamines is described. This protocol proceeds with a CuBr2/TBHP system through a process of oxidative deamination of primary amines to imine and alkynylation, featuring a wide scope of substrates with good functional-group tolerance and operational simplicity. Additionally, the use of two different primary amines could also work smoothly using this protocol.
