Abstract
A concise and enantioselective total synthesis of the Veratrum alkaloid cyclopamine is disclosed. This highly convergent synthesis with a 16-step longest linear sequence (LLS) was enabled by a de novo synthesis of the trans-6,5-heterobicycle via a strain-inducing halocyclization process, a key Tsuji-Trost cyclization to construct the fully substituted, spirocyclic THF motif with exquisite diastereocontrol, and a late-stage ring-closing metathesis (RCM) reaction to forge the central tetrasubstituted olefin.

Abstract
The first general and regioselective Pd-catalyzed cyclocarbonylation to give α-methylene-β-lactones is reported. Key to the success for this process is the use of a specific sterically demanding phosphine ligand based on N-arylated imidazole (L11) in the presence of Pd(MeCN)2 Cl2 as pre-catalyst. A variety of easily available alkynols provide under additive-free conditions the corresponding α-methylene-β-lactones in moderate to good yields with excellent regio- and diastereoselectivity. The applicability of this novel methodology is showcased by the direct carbonylation of biologically active molecules including natural products.

Abstract
Hedgehog (Hh) signaling is involved in the initiation and progression of various cancers and is essential for embryonic and postnatal development. This pathway remains in the quiescent state in adult tissues but gets activated upon inflammation and injuries. Inhibition of Hh signaling pathway using natural and synthetic compounds has provided an attractive approach for treating cancer and inflammatory diseases. While the majority of Hh pathway inhibitors target the transmembrane protein Smoothened (SMO), some small molecules that target the signaling cascade downstream of SMO are of particular interest. Substantial efforts are being made to develop new molecules targeting various components of the Hh signaling pathway. Here, we have discussed the discovery of small molecules as Hh inhibitors from the diverse chemical background. Also, some of the recently identified natural products have been included as a separate section. Extensive structure-activity relationship (SAR) of each chemical class is the focus of this review. Also, clinically advanced molecules are discussed from the last 5 to 7 years. Nanomedicine-based delivery approaches for Hh pathway inhibitors are also discussed concisely.

Abstract
New, small molecule Hedgehog (Hh) pathway inhibitors, such as the furanoditerpenoid taepeenin D, are of high medicinal importance. To establish key structure-activity relationships (SARs) for this lead, a synthetic sequence has been developed for the expedient preparation of several derivatives and their evaluation as Hh inhibitors exploiting its structural similarity to abietic acid. While C(14) substitution is not essential for biological activity, the presence of a hydrogen bond acceptor at C(6) and an intact benzofuran moiety are.

Abstract
Synthesis of four novel (4'R)- and (4'S)- 2'-{[(E)-3β-hydroxyandrost-5-en-17-ylidene]-methyl} oxazolines, comprising 4'-hydroxymethyl (1 and 2) and 4'-methoxycarbonyl (3 and 4) substituents is presented. Reaction of 17α-bromo-21-iodo-3β-acetoxypregn-5-en-20-one with either (L)-serine methyl ester, or (D)-serine methyl ester resulted in methyl N-[3β-acetoxy-21-oxopregna-5,17(20)-dien-21-yl]-(L)-serinate and methyl N-[3β-acetoxy-21-oxopregna-5,17(20)-dien-21-yl]-(D)-serinate (as mixtures of related [17(20)E]- and [17(20)Z]-isomers). Cyclization of obtained amides led to methyl 2'-{[(E)-3β-acetoxyandrost-5-en-17-ylidene]methyl}-(4'S)-4',5'-dihydro-1',3'-oxazole-4'-carboxylate and methyl 2'-{[(E)-3β-acetoxyandrost-5-en-17-ylidene]methyl}-(4'R)-4',5'-dihydro-1',3'-oxazole-4'-carboxylate which were transformed to titled compounds 1-4. The molecular docking of compounds 1-4 to ligand binding site of nuclear receptor LXRβ revealed significant differences due to stereochemical configuration of 4' atom and structure of 4'-substituent.
