rearrangement between readily accessible carboxylic acids and DMSO has been achieved under metal-free conditions in satisfactory to excellent yields. The transformation for the synthesis of valuable methylthiomethyl esters is shown to be a convenient strategy for various (hetero)aromatic acids, α,β-unsaturated carboxylic acids and saturated alkyl carboxylic acids with good functional group tolerance
摘要 在无金属条件下实现了易于获得的羧酸和 DMSO 之间的绿色且具有成本效益的 Pummerer 型重排,收率令人满意。用于合成有价值的甲硫基甲酯的转化被证明是一种方便的策略,可用于各种(杂)芳族酸、α,β-不饱和羧酸和具有良好官能团耐受性的饱和烷基羧酸。图形概要
