A practical synthetic method for the synthesis of vinyl sulfonyl fluorides through copper-promoted direct fluorosulfonylation has been developed. The reaction of the vinylboronic acids with DABSO and then NFSI is performed under mild reaction conditions. This transformation efficiently affords aryl or alkyl vinyl sulfonyl fluorides with good reaction yields, exclusive E-configuration, broad substrate
开发了一种通过铜促进的直接氟磺酰化合成乙烯基磺酰氟的实用合成方法。乙烯基硼酸与DABSO、然后NFSI的反应在温和的反应条件下进行。这种转化有效地提供了芳基或烷基乙烯基磺酰氟,具有良好的反应收率、独特的E构型、广泛的底物范围、优异的相容性和操作简单性。
