CONJUGATE ADDITION OF COPPER(I) ALDIMINES TO α,β-UNSATURATED CARBONYL COMPOUNDS - SYNTHESIS OF 1,4-DIKETONES

Ito, Yoshihiko,Imai, Hiroshie,Matsuura, Takaharu,Saegusa, Takeo

, p. 3091 - 3094 (2007/10/02)

This paper describes the finding that BF3 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
