โฆ Synopsis
A recent report' on the regiospecific reactions of diepoxides with cyanocuprates and the synthetic potential for regiospecific reactions in cycloheptenes prompted us to describe our recent observations on mixed cyanocuprates. Acker' has reported that mixed cyanoalkyl cuprates regiospecifitally open the less substituted and pendant epoxide of diepoxides from substituted 4-vinylcyclohexenes.
Presumably the cyan0 ligand is exerting an unusual effect on the reactivity of organocuprates with different epoxides.

Lithium organocuprates react with 3-alkyl-2,3-epoxy acids (glycidic acids) to afford the products of ring-opening in good yield. The regiochemistry of ringopening is dependent on the stereochemistry of the epoxy acid.
