Photocyclization Reactions. Part 1. Synthesis of Dihydrobenzofuranols Using Photocyclization of 2-Alkoxybenzaldehydes, 2'-Alkoxyacetophenones, 2-Formylphenoxyacetic Acids and 2-Acetylphenoxyacetic Acids

Photocyclization reactions were carried out on 2-alkoxybenzaldehydes 1a-f, 2'-alkoxyacetophenones 2a-h, 2-formylphenoxyacetic acids 1i-l and 2-acetylphenoxyacetic acids 2i-m.Irradiation opf 1a-f and 2a-h in acetonitrile gave the corresponding dihydrobenzofuranols 3, 5 and dihydroisobenzofuranols 4, 6.Using carboxylic acids 1i-l, 2i-m as starting materials, decarboxylation occurred immediately to give the corresponding ethers 1a-d, 2a-e.Further irradiation of the solution afforded dihydrobenzofuranols 3,5 and dihydroisobenzofuranols 4, 6.Substituent effects on photocyclization and reaction pathways are discussed.
