Upon exposure to potassium hydride in THF in the presence of 18-crown-6, several 2-cyano-1-vinylcycloalkanol derivatives were found to undergo ring enlargement to give the corresponding γ-cyano cycloalkanones in synthetically useful yields.

Herein, we describe the diastereoselective synthesis of five- and six-membered α,α-disubstitutedcyclic β-hydroxy nitriles and their resolution via enzymatic transesterification. By this method, all possible stereoisomers were obtained in enantiopure form and high yield.
