The cyclo-γ-cyanoethylation of 3β-acetoxy-D-homo-5α-pregn-17a-en-21-al is reported. It is shown that the orientation of the cyanoethylation of 2-cycloalkyl-substituted ethenals does not significantly depend on the ring size of the cycloalkyl substituent. It is further shown that the stereochemistry of the cyclohexadienonitrile obtained by dehydration of the main reaction products seems to be, in the case of a fusion to a six-membered ring, in agreement with Moscowitz' rule relating the helicity of the chromophore to the sign of its Cotton effect, in contradistinction to the situation in the case of a system in which one of the double bonds of the chromophore is exocyclic to a five-membered ring.
