Yang, Peng;Wang, Qiang;Cui, Bing-Hui;Zhang, Xiao-Dong;Liu, Hang;Zhang, Yue-Yuan;Liu, Jia-Liang;Huang, Wen-Yu;Liang, Ren-Xiao;Jia, Yi-Xia research published 《 Enantioselective Dearomative [3 + 2] Umpolung Annulation of N-Heteroarenes with Alkynes》, the research content is summarized as follows. Enantioselective [3 + 2] annulation of N-heteroarenes such as 2-(2-bromophenyl)quinoline with alkynes R1CCR2 [R1 = Me, Ph, benzyloxymethyl, (thiophen-2-ylmethoxy)methyl, etc.; R2 = Me, Ph, benzyloxymethyl, (thiophen-2-ylmethoxy)methyl, etc.] has been developed via a cobalt-catalyzed dearomative umpolung strategy in the presence of chiral ligand e.g., [(2R,3R)-3-(diphenylphosphanyl)butan-2-yl]diphenylphosphane and reducing reagent. A variety of electron-deficient N-heteroarenes e.g., 2-(2-bromophenyl)quinoline and internal or terminal alkynes are employed in this reaction, showing a broad substrate scope and good functionality tolerance. Annulation of electron-rich indoles I (R = H, 5-Cl) with alkynes is also developed. This protocol provides a straightforward access to a variety of N-spiroheterocyclic mols. such as II and in excellent enantioselectivities (76 examples, up to 99% ee).
