We streamline the synthesis of ketones and esters with multiple α-heteroatoms by sequentially generating two heteroatom metal carbenes using a designer I(III)/S(VI) reagent. This strategy enables the selective addition of oxygen, nitrogen, sulfur, or carbon atoms, incorporating up to three functional groups at the α-carbon of carbonyls in a single step.
我们通过使用 I (III) /S (VI)设计试剂依次生成两个杂原子金属卡宾,简化了具有多个 α-杂原子的酮和酯的合成。该策略能够选择性地添加氧、氮、硫或碳原子,一步即可在羰基的 α-碳上结合多达三个官能团。
