Abstract

Pterosin E (2,5,7-trimethyl-1-oxoindan-6-ylacetic acid)(Ia), a naturally occurring sesquiterpenoid has been synthesized starting from -bromomesitylene (IIIa). Alkylation of diethyl methylmalonate with (IIIa) gave the diester (IIIb) which was converted into the cyanomethyl diester (IVb). Hydrolysis of (IVb) to the dicarboxylic acid (V) followed by its cyclodehydration gave pterosin E.
