tertiary amides, including the biologically active aryl-phenazine carboxamides and the challenging non-heterocyclic carbonyl functions, using low-cost hydrosilane as a reducing reagent has been developed. The novel catalyst system exhibits high efficiency and exclusive selectivity, providing the desired amines in useful to excellent yields under mild conditions. Overall, this transition metal-free process
已开发出使用低成本的氢硅烷作为还原剂,对各种未活化的叔酰胺(包括生物活性芳基-吩嗪羧酰胺和具有挑战性的非杂环羰基官能团)进行氢化物催化的还原裂解反应。该新型催化剂体系显示出高效率和排他选择性,在温和条件下以有用的目的提供所需的胺以优异的产率。总的来说,这种无过渡金属的方法可以为目前使用的昂贵的还原剂,高压氢或金属系统提供多种选择,以进行酰胺的选择性还原裂解。
