Conjugate addition [1] of a nucleophile to a polyconjugated carbonyl compound is an intriguing reaction as it can potentially result in CΓ€C bond formation at one of the remote carbon atoms. In many cases, however, the regioselectivity may be poor, unpredictable, or condition-dependent, and the origi

at low temperature, allylic lithium organocuprates and allylic organocopper(1) compounds add stereoselectively (cisaddition)to a-acetylenic esters to afford a,&-biethylenic esters. Lithium organocuprates react at low temperature nit esters to give a-ethylenic esters corresponding to R2CuLi + R'-CK-C
