Photochemical Synthesis and Antimicrobial Activity of Dihydrobenzofuranols from 2-Alkoxy Substituted Benzophenones and Ethyl-2-Aroyl Aryloxy Acetates 1
Upon UV irradiation 2-alkoxy substituted benzophenones 2a–f and ethyl-2-aroyl aryloxy acetates 7a–c, in acetonitrile under went intramolecular δ hydrogen abstraction and led to synthesis of solely dihydrobenzofuranols 6a–f and 11a–c in excellent yield with potent antimicrobial activity.
