Abstract A novel and efficient method for the synthesis of amide has been developed. The reactions proceeded smoothly under aqueous conditions at room temperature and generated the corresponding products in good to excellent yields. It is worth noting that alkyl amines which did not react in known approaches are well tolerated in our system.

The first metal free report on the amidation of aldehydes with aminopyridines was accomplished using simple aqueoushydrogenperoxide (aq. H2O2) as the oxidant. No catalysts or additives were needed for this transformation and the reaction proceeded in water, an environmentally benign reaction medium. Green oxidant and reaction conditions, and the ability to construct diverse N-(pyridin-2-yl)benzamide
关于醛与氨基吡啶酰胺化的第一个无金属报告是使用简单的过氧化氢水溶液(H 2 O 2水溶液)作为氧化剂完成的。该转化不需要催化剂或添加剂,并且反应在环境友好的水介质中进行。绿色的氧化剂和反应条件,以及通过这种优美的方法构建各种N-(吡啶-2-基)苯甲酰胺的能力,使其成为合成这些酰胺的实用替代品。
