A highly regioselective and catalyst-free sulfonation of allylic alcohols with sulfinyl amides has been realized. Such a mix-and-go procedure provides a convenient approach to synthetically various allylic sulfones under mild reaction conditions. Furthermore, this novel reaction shows ample substrate scope and outstanding functional group tolerance and could also be scaled-up. Meanwhile, it is the
已经实现了烯丙醇与亚磺酰胺的高度区域选择性和无催化剂磺化。这种混合和去过程为在温和的反应条件下合成各种烯丙基砜提供了一种方便的方法。此外,这种新颖的反应显示出充足的底物范围和出色的官能团耐受性,并且还可以放大。同时,这是亚磺酰胺在反应中作为强硫亲核试剂的第一个例子。1,1,1,3,3,3-Hexafluoro-2-propanol (HFIP) 作为溶剂在烯丙基磺化中起关键作用。
