Abstract
Since the initial report, the Friedel-Crafts reaction has become a powerful tool to functionalize arenes. Nevertheless, the use of nitrogen heterocycles as electrophiles in Friedel-Crafts reactions has been less explored. Here, we show a Friedel-Crafts-like reaction of electron-rich arenes with quinazolin-4(3H)-ones, enabling late-stage C2-H arylation of quinazolin-4(3H)-ones via triflic anhydride (Tf2O) activation. A series of substrates can be efficiently coupled under mild reaction conditions, affording C(sp3)-C(sp2) coupling product 2-aryl dihydroquinazolinones that can be further converted into the corresponding quinazolinone in the presence of base. This methodology offers efficient access to 2-aryl quinazolin-4(3H)-ones and exhibits good functional group compatibility and site selectivity. Mechanistic investigations reveal the formation of highly electrophilic iminium intermediates upon Tf2O activation of quinazolin-4(3H)-ones, which serve as the key reactive species, enabling the Friedel-Crafts reaction to proceed efficiently.

Abstract
The synthesis, characterization, and catalytic application of a new phosphine-free, well-defined, water-soluble, and air-stable Mn(II)-catalyst [Mn(L)(H2O)2Cl](Cl) ([1]Cl) featuring a 1,10-phenanthroline based tridentate pincer ligand, 2-(1H-pyrazol-1-yl)-1,10-phenanthroline (L), in dehydrogenative functionalization of alcohols to various N-heterocycles such as quinazolin-4(3H)-ones, quinolines, and quinoxalines are reported here. A wide array of multisubstituted quinazolin-4(3H)-ones were prepared in water under air following two pathways via the dehydrogenative coupling of alcohols with 2-aminobenzamides and 2-aminobenzonitriles, respectively. 2-Aminobenzyl alcohol and ketones bearing active methylene group were used as coupling partners for synthesizing quinoline derivatives, and various quinoxaline derivatives were prepared by coupling vicinal diols and 1,2-diamines. In all cases, the reaction proceeded smoothly using our Mn(II)-catalyst [1]Cl in water under air, affording the desired N-heterocycles in satisfactory yields starting from cheap and readily accessible precursors. Gram-scale synthesis of the compounds indicates the industrial relevance of our synthetic strategy. Control experiments were performed to understand and unveil the plausible reaction mechanism.

Abstract
The sphingomyelin pathway is important in cell regulation and determining cellular fate. Inhibition of sphingosine kinase isoform 1 (SK1) within this pathway, leads to a buildup of sphingosine and ceramide, two molecules directly linked to cell apoptosis, while decreasing the intracellular concentration of sphingosine-1-phosphate (S1P), a molecule linked to cellular proliferation. Recently, an inhibitor capable of inhibiting SK1 in vitro was identified, but also shown to be ineffective in vivo. A set of compounds designed to assess the impact of synthetic modifications to the hydroxynaphthalene ring region of the template inhibitor with SK1 to obtain a compound with increased efficacy in vivo. Of these fifteen compounds, 4A was shown to have an IC50 = 6.55 μM with improved solubility and in vivo potential.

Abstract
Direct C(sp2)-H functionalization of the endocyclic azomethine and aldonitrone moieties in non-aromatic azaheterocycles has established itself as a promising methodology over the last decade. Transition metal-catalyzed cross-coupling reactions, α-metalation-electrophile quenching protocols, and (metal-free) nucleophilic substitution of hydrogen reactions (SNH) are the major routes applied on cyclic imines and their derivatives. In this overview, we show the tangible progress made in this area during the period from 2008 to 2020.

Abstract
Cross-coupling reactions furnishing carbon–carbon (C–C) and carbon–heteroatom (C–X) bond is one of the most challenging tasks in organic syntheses. The early developed reaction protocols by Ullmann, Ullman–Goldberg, Cadiot–Chodkiewicz, Castro–Stephens, and Corey–House, utilizing elemental copper or its salts as catalyst have, for decades, attracted and inspired scientists. However, these reactions were suffering from the range of functional groups tolerated as well as severely restricted by the harsh reaction conditions often required high temperatures (150–200 °C) for extended reaction time. Enormous efforts have been paid to develop and achieve more sustainable reaction conditions by applying the microwave irradiation. The use of controlled microwave heating dramatically reduces the time required and therefore resulting in increase in the yield as well as the efficiency of the reaction. This review is mainly focuses on the recent advances and applications of copper catalyzed cross-coupling generation of carbon–carbon and carbon–heteroatom bond under microwave technology.

Abstract
Copper-catalyzed Csp2–Csp2 bond forming reactions through C–H activation are still one of the most useful strategies for the diversification of heterocyclic moieties using various coupling partners. A catalytic protocol for the C–H (hetero)arylation of thiazolo[5,4-f]quinazolin-9(8H)-ones and more generally fused-pyrimidinones using catalyst loading of CuI with diaryliodonium triflates as aryl source under microwave irradiation has been disclosed. The selectivity of the transfer of the aryl group was also disclosed in the case of unsymmetrical diaryliodonium salts. Specific phenylation of valuable fused-pyrimidinones including quinazolinone are provided. This strategy enables a rapid access to an array of various (hetero)arylated N-containing polyheteroaromatics as new potential bioactive compounds.

Abstract
Conventionally, the organic reactions are accomplished by conductive heating with an external
heat source like an oil bath. On the contrary, since its inception, the application of microwave
irradiation is growing as a suitable alternate heating method in organic synthesis. Microwave heating
considerably reduces the reaction time without promoting any side reactions. The fundamental synthetic
organic chemistry majorly deals with transition-metal-catalyzed C–C and C–heteroatom bond
formation reactions. It is one of the most important methods in contemporary chemistry resulting in a
tremendous increment in the applications of these reactions during the last few years. This field has
been acknowledged with a number of Nobel Prizes during the last decade (2001, 2005 and 2010). A
considerable effort has been done on the continuous development of new ligands and catalysts as
well as an increased understanding of the mechanisms for the improvement of the reaction condition.
This review focuses on some of the latest developments in the area of cross-coupling reactions aided
by microwave irradiation.

Abstract
A Ru or Rh-catalyzed efficient and atom-economic C7 allylation of indolines with vinylcyclopropanes was developed via sequential C–H and C–C activation. A wide range of substrates were well tolerated to afford the corresponding allylated indolines in high yields and E/Z selectivities under microwave irradiation. The obtained allylated indolines could further undergo transformations to afford various value-added chemicals. Importantly, this reaction proceeded at room temperature under solvent-free conditions. A Ru or Rh-catalyzed direct C7 allylation of indolines with vinylcyclopropanes via sequential C–H/C–C activation under microwave irradiation has been disclosed.![]()

Abstract
Copper-catalyzed oxidative couplings of N-allylbenzamides for C-N and C-O bond formations have been developed through C-H bond functionalization. To demonstrate the utility of this approach, it was applied to the synthesis of β-aminoimides and imides. To the best of our knowledge, these are the first examples in which different classes of N-containing compounds have been directly prepared from the readily available N-allylbenzamides using an inexpensive catalyst/oxidant/base (CuSO4 /TBHP/Cs2 CO3 ) system.

Abstract
A versatile and practical “on-water” protocol was newly developed to synthesize quinazolinones using o-bromobenzonitrile as a novel starting material. Studies have found that air as well as water plays an important role in synthesis of quinazolinones. Further investigation indicated that dihydroquinazolinones can be prepared with this protocol under the protection of N2. The protocol can be extended to other substrates and various quinazolinones and dihydroquinazolinones were obtained. o-Bromobenzamide, o-aminobenzonitrile, and o-aminobenzamide were also evaluated as starting materials, and the results further proved the versatility of this protocol, especially towards dihydroquinazolinones.

Abstract
A selective functionalization of thiazolo[5,4-f]quinazolin-9(8H)-one has been developed through sequential activation of C-H bonds to furnish diarylated compounds. This strategy allows the regioselective C2 and C7 arylation by a judicious choice of coupling partners and bases, requiring no additional ligands or directing groups. Differently substituted N(8)-benzylated-2,7-diaryl-thiazoloquinazolin-9(8H)-ones were thereby obtained in a facile manner. A one-pot procedure was also performed. These protocols provide a synthetically useful route for late-stage functionalization of this highly valuable scaffold, required in drug discovery.
