An unprecedented construction of benzo[d][1,3]oxathiin-4-ones through skeletal editing of benzodithiol-3-ones is described herein, which represents the first example for swapping from S atom to C-O entities. This organic phosphine promoted skeletal editing of benzodithiol-3-ones enables to forge a range of benzo[d][1,3]oxathiin-4-ones by using aldehydes as readily available cyclization partners. This novel skeletal editing strategy distinguishes as mild conditions, unnecessary inert gas protection, convenient operation, decent yields and good functional group compatibility.

用于组装苯并[d][1,3]oxathiin-4-ones的Benzodithiol-3-ones的骨架编辑


本文描述了通过对苯并二硫醇-3-酮进行骨架编辑而前所未有地构建苯并[d][1,3]氧硫因-4-酮，这代表了从S原子交换为C-O实体的第一个例子。这种有机膦促进苯并二硫醇-3-酮的骨架编辑，通过使用醛作为容易获得的环化伙伴，能够形成一系列苯并[d][1,3]氧硫因-4-酮。这种新颖的骨架编辑策略具有条件温和、无需惰性气体保护、操作方便、产量高、官能团兼容性好的特点。
