Photochemical reactions of 2-substituted furans I, IV and V with benzaldehyde, benzophenone and 4-methylbenzophenone gave substituted 2,7-dioxabicyklo-3-heptenes, which can be used for syntheses of 2,3- or 2,4-disubstituted furans.Regioisomeric (2:1)-cycloadducts XV and XVI were distinguished on the basis of their 1H and 13C NMR spectra.

It has been possible to prepare oxetanes from several carbonyl compounds and derivatives of furan, pyrrole and thiophene.This account summarizes the successful and some of the unsuccessful attempts carried out in this laboratory to extend the Paterno-Buechi reaction to the common five-membered heterocyclic systems; the new compounds obtained in this connection are reported and several interesting facts which may help inderstand the reactivity of heterocycles in the presence of excited carbonyl compounds are commented.
