A novel gallium/samarium-mediated coupling of epoxides with allyl halides in aqueous media and synthesis of homoallylic alcohols
A mild and efficient protocol for the coupling of various substituted epoxides 1 with allylgallium reagent generated in situ in a Bu4NBr-DMF-H2O system have been developed. The coupling is also found to be equally effective when samarium is used in lieu of gallium and the corresponding homoallylic alcohols 2 were obtained in almost comparable yields.
