摘要

2-Vinyloxiranes have been found to be excellent surrogates to β, γ-unsaturated aldehydes. These valuable electrophiles, generated in situ by treatment of a 2-vinyloxirane with a catalytic amount of Sc (OTf) 3, are effectively trapped by the chiral allylating agents based on α-pinene, affording bishomoallylic alcohols in high yield and excellent selectivity.
