Abstract

A range of 2-alkyl-2-cyclopentcn-1-ones including the pl '() Slilgl2ll'ldlI\ precursor 2-(6- mcth0xycarbonylhexyl)-2-cyclopenten-l-one and the jasmorioid precursor 2-[(Z)-2-pentenyl]- 2~ cyclopenten-1-one, have been prepared by a short synthetic route which begins with 6-- methyl-5-hcplen-2-one and generates the key 1, 4-ketoaldehyde intermediates by a kinetic alkylation--ozonolysis procedure.
