Synthesis of pyrenocycloalkenes by using [2 + 2] photocycloaddition to pyrene and Diels–Alder reaction
Photoreaction of pyrene 1 with methyl cinnamate 15a gave a photocycloadduct 16a at 4,5-position of pyrene stereoselectively. Oxidation of 16a using DDQ yielded a pyrenocyclobutene derivative 18a. Functional group conversion of the ester moiety of 18a resulted in the synthesis of carboxylic acid 19,...
