Aza-(2,3)-Sigmatropic Rearrangement of Phosphoramides.

Abstract The aza-[2,3] sigmatropic rearrangement was realized by using a phosphoramide group as a stabilization group of the carbanion. Not only ( E )-substituted alkene, but also ( Z )-, and trisubstituted alkene can be used as substrates. © 1997 Elsevier Science Ltd.
