A manganese-catalyzed hydrogenation of esters has been accomplished with TONs up to 1000, using cheap, environmentally benign, potassium carbonate and simple alcohols as activator and solvent, respectively. The weakly basic conditions lead to good functional group tolerance and enable the hydrogenation of enantiomerically enriched α-chiral esters with essentially no loss of stereochemical integrity
锰的酯催化氢化反应已完成,TONs的用量高达1000,分别使用廉价,对环境无害的碳酸钾和简单的醇作为活化剂和溶剂。弱碱性条件导致良好的官能团耐受性,并能够氢化对映异构体富集的α-手性酯,而基本上不损失立体化学完整性。
