✦ Synopsis

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-COOC2H5 V
