preparing of (E)-vinyl sulfones via PhI(OAc)2-mediated decomposition of ketone-derived N-arylsulfonyl hydrazones has been developed. The generation of α- or β-substituted vinyl sulfones was affected by the steric hindrance at β-position of the substrates. This transformation provides an environment-friendly and important complementary strategy for the synthesis of various (E)-vinyl sulfones.
已经开发了一种新颖且有效的方法,该方法通过PhI(OAc)2介导的酮衍生的N-芳基磺酰基yl的分解来制备(E)-乙烯基砜。α-或β-取代的乙烯基砜的产生受到底物在β-位置的位阻的影响。该转化为合成各种(E)-乙烯基砜提供了环境友好的重要补充策略。
