Aerobicoxidation of aldehydes to 1,2‐ and 1,3‐diol monoesters was catalyzed by polymer‐incarcerated gold nanoclusters under ambient conditions. The esterification proceeded much faster with 1,2‐ and 1,3‐diols and their derivatives rather than with methanol.

A mild and efficient reaction for synthesizing esters from thioamide precursors has been established. This method is accomplished in one pot under mild conditions. The process involves the alkylation and activation of inert thioamides, which leads to the cleavage of stable C–N and C–S bonds, eventually resulting in valuable esters with a broad range of substrates. The transformation can be easily carried out at room temperature using thioamide substrates, reactants, and activating agents. This protocol has been demonstrated by synthesizing important esters with applications.
