✦ Synopsis

Photochemical cycloaddition reactions of acetylene esters and fused ring heteroaromatic compounds of the general structure (I) have been under extensive investigation in our laboratories.lo3 Cur results demonstrate that sensitized photocycloaddition to benzo(b)thiophene X=O,S,N-R; R=alkyl and many of its alkylated derivatives, as well as the anologus benzo@)furans, give b1~+21;] adducts which are capable of secondary photochemical allylic rearrangements.
