Synthése, stéréochimie, et réactivité thermique de (<i>N</i>‐méthylidenealkylamino)‐2 aziridines

Abstract

Abstract 1‐Alkyl‐2‐( N ‐methylidenealkylamino)aziridines are obtained by the reaction of primary amines with either α‐chloroacraldehyde or α‐chlorocrotonaldehyde. Structural assignments are made by nmr spectroscopy. The thermal rearrangement of 1‐alkyl‐2‐( N ‐methylidenealkylamino)‐3‐methylaziridines to pyrroles is described.
