Organic Photochemical Reactions. I. The Synthesis of Substituted Oxetanes by the Photoaddition of Aldehydes to Furans

Abstract
The photochemical reaction of aldehydes (propionaldehyde and benzaldehyde) and furan have been studied in the liquid phase; two new compounds, oxetanes I and II have easily been produced with a high purity by this photo-reaction. In the case of 2-methylfuran and propionaldehyde (or benzaldehyde), a mixture of oxetanes III and IV (or V and VI) has also been obtained.
