Abstract

In conjunction with our studies of the amidoalkylation reaction,'multigram quantities of N-acyl- 2-pyrrolines (1) were needed. Interestingly, only a few methods for the synthesis of this class of compounds had been reported. Stille and co-workers prepared 1 by a novel transition metal mediated isomerization of N-acyl-3-pyrrolines2 and also cyclized (acy1amino) butyraldehydes to produce le3 Although these methods are excellent for qmall-scale ...
