Synthesis of natural fragrant molecules cis-3-methyl-4-decanolide and aerangis lactone. General enantioselective routes to beta,gamma-cis-disubstituted gamma-lactones and gamma,delta-cis-disubstituted delta-lactones

Research has been conducted on the fragrant target molecules, cis-3-methyl-4-decanolide and aerangis lactone. The route to these molecules which does not require air-sensitive reagents has been developed and the details are presented.
