Sulfur alkylation of N-acyl sulfenamides with alkyl halides provides sulfilimines in 47% to 98% yields. A broad scope was established with a variety of aryl and alkyl sulfenamides, including for different N-acyl groups. Alkyl halides with different steric and electronic properties were effective inputs, including methyl, primary, secondary, benzyl, and propargyl halides. A proof-of-concept asymmetric
N-酰基次磺酰胺与烷基卤化物的硫烷基化得到硫亚胺,产率为 47% 至 98%。各种芳基和烷基亚磺酰胺建立了广泛的范围,包括不同的N-酰基。具有不同空间和电子性质的烷基卤化物是有效的输入,包括甲基卤化物、伯卤化物、仲卤化物、苄基卤化物和炔丙基卤化物。还演示了不对称相转移烷基化的概念验证。硫亚胺产物很容易转化为N-酰基和游离亚砜亚胺,这代表了药物化学中的重要基序。
