Tricyclic aromatic ketones by cycliacylation of carboxylic acid derivatives of indan, tetralin, and benzosuberane

Abstract

The synthesis of a homologous series of new carboxylic acids substituted in the α-position of indan, tetralin, and benzosuberane is accomplished using an efficient general procedure. Cycliacylation of these acids and their corresponding β-isomers produces a complete series of tricyclic aromatic ketones.
