Abstract

Abstract This paper describes the finding that BF 3 etherate effectuates the conjugate additions of copper (I) aldimines, generated in situ from lithium aldimines and Cu (I) halide, to α, β-unsaturated carbonyl compounds to produce 4-(N-alkylimino)-ketones, which give on acid hydrolysis 1, 4-diketone derivatives.
