Cyclic homoaldol products have been prepared viaconjugateaddition of α-alkoxyorganocuprate reagents to enones. The reactions are regiospecific, providing the homoaldol products in good to excellent yields. The preparation of the cuprates from the α-alkoxyorganostannane precursor is described in detail. Best results were obtained with the higher order cyano cuprate reagent using in-situ trimethylsilyl
