Michael Addition of Acyclic Lithium 1,3-Dien-2-olates with α,β-Unsaturated Esters, Ketones, and Diesters

Article abstract of DOI:10.1246/bcsj.64.2990

The Michael addition of lithium 1,3-dien-2-olates with α,β-unsaturated carbonyl compounds is described.With α,β-unsaturated esters the reaction was reversible even at -78 deg C, while kinetically controlled with α,β-unsaturated ketones or alkylidenemalona
