โœฆ Synopsis

Epoxides react smoothly with tetraallyltin in the presence of 2 mol% of Bi(OTf) 3 under mild reaction conditions to afford the corresponding homoallylic alcohols in excellent yields with high regioselectivity while aryl aziridines produce exclusively allyl amines in good yields under similar conditions.

Anhydrous ytterbium(III) triflate-catalyzed ring opening of aromatic 1,2-epoxides with allyltributyltin in THF results in the formation of bishomoallyl alcohols in excellent yields and with complete regioselectivity. The results are compared with those obtained with allylmagnesium bromide as allylat
