摘要

Abstract 3-Methoxyindolenines derived from 2-methyl-3-alkylindoles by bromination- methanolysis undergo base induced alkylations and aldol condensations at the C-2 methyl group. The modified indolenines can be efficiently converted to C-2-sides chain alkylated indoles by reduction with lithium-aluminum hydride or zinc.
