Abstract
Abstract Irradiation of 3-alkenyloxy-5-irydroxybenzoic and the corresponding 3-alkenyloxy-5-methoxybenzoic acid derivatives 1 – 4 in the presence of small quantities of H2SO4 produces highly functionalized alkyloxyenones 6 – 8 in good or moderate yields. The products are explained via an acid catalyzed transformation of the primary [2+2] photocycloadducts.
