摘要

The preparation and Birch reduction of a series of electron-deficient pyrroles is described. This methodology allows the synthesis of a variety of C-2 substituted 3-pyrrolines []‡ in good to excellent yields. The role of various activating groups (amide, ester, carbamate and urea) has been examined with regard to bot
