Photocarboxylation of 4H-cyclopentaphenanthrene by carbon dioxide in the presence of N,N-dimethylaniline in dimethyl sulfoxide afforded 8,9-dihydro-4H-cyclopentaphenanthrene-8- and 2-carboxyl acid, and 4H-cyclopentaphenanthrene-8-carboxylic acid.These acids were derived into methyl-4H-cyclopentaphenanthrenes.
