Enantioselective epoxidation of β,γ-unsaturated carboxylicacids with a cooperative binuclear titanium complex has been developed to provide single diastereomer γ-lactones in high yields and enantioselectivities via intramolecular cyclization. For the success of the reaction, the proper distance between the carboxylicacid and alkene is quite important, offering the regioselective epoxidation of unsaturated
Dienoic acids are prepared by reaction of salts of 3-butenoic acid and vinyl halides, in the presence of catalysts which are phosphinic complexes of rhodium or nickel.
