An air-assisted, functional-group-driven, mild, additive-free, three-component synthetic approach to different 2-oxoacetamidines from 2-oxoaldehydes, secondary amines, and anilines was successfully developed. Mechanistically, the transformation proceeds through a highly unstable system ((RCOCHNN2)-N-1) that rearranges at room temperature and undergoes air-assisted dehydrogenation to different 2-oxo
Abstract Herein, we report a Zinc catalyzed double carbonylation of aryliodides with secondary amines under CO pressure for the synthesis of α-ketoamides in good to excellent yields. This methodology provides a simple and economic approach to derivatize useful α-ketoamides.
