In this study, a multicomponent reaction via the Mannich intermediate was developed using methanol, secondary amine, and sulfonamide as starting materials. This method uses methanol as a green C1 source. The substrate scope is wide, and the yield is good. The mechanistic study shows that methanol generates formaldehyde under electrochemical conditions, and sulfonyl amidine as a nucleophile reacts with
在这项研究中,使用甲醇、仲胺和磺酰胺作为起始原料,开发了通过曼尼希中间体的多组分反应。该方法使用甲醇作为绿色C1源。底物范围广,成品率好。机理研究表明,甲醇在电化学条件下生成甲醛,磺酰脒作为亲核试剂与席夫碱中间体一步反应生成N-磺酰脒。
