The unique structure of oxyallyls represents a significant challenge for their catalytic asymmetric applications. Herein, an unprecedented chiral imidodiphosphoric acid-catalytic enantioselective (3 + 3) cycloaddition between oxyallyl zwitterions generate
Tandem amination/cycloisomerization of aryl propargylic alcohols with 2-aminopyridines as an expedient route to imidazo[1,2-a]pyridines
Liu, Ping,Deng, Chun-Lin,Lei, Xinsheng,Lin, Guo-Qiang
experimental part, p. 7308 - 7316 (2012/01/06)
A new tandem route leading to imidazo[1,2-a]pyridines has been explored through the direct amination of aryl propargylic alcohols with 2-aminopyridines and their subsequent intramolecular cycloisomerization. A ZnCl2/CuCl system has been develop
