In the presence of a catalytic amount of trityl salt, allylstannanes and stannylated enolates smoothly react with 2-(2-ethylthioalkylidene)-1,3-dithiolane, synthetic equivalent of α,β-unsaturated ester, to afford the corresponding adducts in good yields, respectively.
在一定量的三苯甲基盐催化下,烯丙基锡和锡化烯醇与 2-(2-乙硫基亚烷基)-1,3-二硫环(α,β-不饱和酯的合成等价物)顺利反应,分别以良好的产率获得相应的加合物。
