A novel approach towards the synthesis of α-ketoamides using tertiary amines as nitrogen group sources via C–N bond cleavage has been developed. In the presence of Ag2CO3 and K2S2O8, α-keto acids reacted with tertiary amines to afford the corresponding α-ketoamides in good yields.
已经开发出一种通过叔胺作为氮基源通过C–N键断裂合成α-酮酰胺的新方法。在Ag 2 CO 3和K 2 S 2 O 8的存在下,α-酮酸与叔胺反应以良好的产率得到相应的α-酮酰胺。

visible-light induced directamidation of benzoylformic acids with tertiary amines has been explored. Tertiary amines underwent N-dealkylative amidation with α-ketoacid in the presence of [IrdFCF3ppy}2(bpy)]PF6 and Cs2CO3, affording the corresponding α-ketoamides in good yields under mild conditions. This transformation exhibits a wide substrate scope and provides a facile synthetic approach to α-ketoamides
已经研究了可见光诱导的苯甲酰基甲酸与叔胺的直接酰胺化。叔胺在[Ir dFCF 3 ppy} 2(bpy)] PF 6和Cs 2 CO 3的存在下用α-酮酸进行N-脱烷基酰胺化反应,在温和条件下以良好的收率得到相应的α-酮酰胺。这种转化表现出广泛的底物范围,并为α-酮酰胺提供了一种简便的合成方法。

Dinuclear palladium complexes bridged by a novel PNNP ligand, N,N′-bis[(2-diphenylphosphino)phenylformamidinate (dpfam), were found to be very efficient and selective catalysts for the doublecarbonylation of iodobenzene with diethylamine using K3PO4 as base and 1,4-dioxane as solvent with a TON up to 105 and selectivity of 96%.
已发现由新型PNNP配体N,N'-双[(2-二苯基膦基)苯基甲ami酸盐(dpfam)桥接的双核钯络合物是非常有效的选择性催化剂,可使用K 3 PO 4作为二乙胺与二乙胺进行双羰基化反应。碱和1,4-二恶烷作为溶剂,TON高达10 5,选择性为96%。

carbonylation protocol usingheterogeneous Pd0 nanoparticles supported on the metal–organicframeworks (MOFs) MIL‐88B‐NH2 (Fe/Cr). The synthesis of a vast array of carbonyls, which includes amides, esters, carboxylic acids, and α‐ketoamides, was achieved through mono‐ and dicarbonylation reactions. The selectivity could be controlled simply by tuning the reaction conditions. Superior activity and selectivity
