  Remarkable difference in reactivity of ordinary vinylcopper reagents and vinylzinc halide containing a copper salt towards γ-mesyloxy-α, β-enoates. Synthesis of homochiral 1,4-dienes

  摘要：

  Whereas the reaction of gamma-mesyloxy alpha,beta-enoates with vinyl-Cu(CN)M or (vinyl)2Cu(CN)M2 (M = Li or MgX) yielded a reduction product with an (E)-double bond at the beta,gamma-position, treatment of the same substrates with ''higher order'' zinc cuprate reagents or vinyl-ZnCl by the addition of catalytic amount of Cu(I) or Cu(II) salt afforded alpha- and gamma-vinylation products. Both vinylation products were stable 1,4-diene derivatives that are only more difficulty accessed by more traditional means.
