Direct Access to Functionalized Cyclic Enones Using Mannich, Morita-Baylis-Hillman and Elimination Reactions

Abstract

A series of highly functionalized cyclic enones were obtained from Mannich, Morita-Baylis-Hillman and elimination reaction with cyclic enones.

Key words

Morita-Baylis-Hillman - cyclic enones - aminals - Mannich reactions - concavine
