We have developed an efficient synthesis of β-halo Z-sulfonyl alkenes via hydrohalogenations of readily available sulfonyl alkynes. The high hydrogen bonding acidity of linear acetic acid network or aggregate may play a vital role in activation of sulfonyl alkyne substrates. Our condition offers high stereoselectivity, good chemical yields, and high functional group tolerance.

氢键网络辅助磺酰基炔烃的区域和立体控制的氢卤代反应

我们已经通过容易获得的磺酰基炔烃的氢卤化作用开发了一种β-卤代Z-磺酰基烯烃的有效合成方法。线性乙酸网络或聚集体的高氢键酸度可能在磺酰基炔烃底物的活化中起重要作用。我们的条件提供了较高的立体选择性，良好的化学收率和较高的官能团耐受性。
