Abstract

An efficient Y(OTf)3-catalyzed generation of azometh­ine ylides from donor–acceptor aziridines and their [3+2] cyclo­addition with imines was developed. The method provides facile access to multisubstituted imidazolidines, which have been extensively used in organic synthesis. Furthermore, a three-component reaction on a gram scale and an asymmetric variation were also developed in this work.
