Michael Addition of Selenoamides to α,β-Unsaturated Carbonyl Compounds: Stereocontrolled Synthesis of δ-Oxo Selenoamides and Their Reactivity

Abstract
[reaction: see text] Lithium eneselenolates generated from selenoamides underwent Michael addition to alpha,beta-unsaturated esters and ketones with high diastereoselectivity to give delta-oxo selenoamides in moderate to high yields within a few seconds. Further selective transformations of the delta-oxo selenoamides were also achieved.
