文摘An efficient chiral Br?nsted acid-catalyzed conjugate addition of indoles to azadienes has been successfully developed,which enables a facile approach to optically active hetero-triarylmethanes with excellent enantioselectivities and broad substrate scope.This chiral Br?nsted acid catalytic system provides a new opportunity for the development of asymmetric reactions of azadienes.
