Abstract
The anodic oxidation of the lithium amides of δ-alkenylamines 6a, 6b, 6c, 10a, and 10b gave stereoselectively cis-5-substituted 2-benzyl-1-methylpyrrolidines (7a, 7b, 7c) and 4- substituted 2-benzyl-1-methyl-pyrrolidines (11a, 11b) in high yields. The anodic oxidation of N-methoxyl compounds of δ-alkenylamines (12a, 12b) gave 5-substituted 2-benzoyl-1- methylpyrrolidines (13a, 13b).
