Abstract
3-(Silyloxy)oxetanes are obtained by irradiating mixtures of aromatic aldehydes and silyl enol ethers in benzene as the solvent. Under similar conditions, but in acetonitrile rather than benzene, the Paternò-Büchi reaction of N-acyl enamines gives the corresponding protected 3-aminooxetanes. The reactions occur with high diastereoselectivity.
