Copper-Catalyzed One-Pot Synthesis of α-Ketoamides from 1-Arylethanols
摘要:
A copper-catalyzed one-pot strategy for the synthesis of -ketoamides from 1-arylethanols is described. This triple oxidation of 1-arylethanols involves alcohol oxidation, sp(3) C-H oxidation, and oxidative amidation with amines. The protocol is highly efficient, delivering -ketoamides in good to excellent yields.

A metal-free oxidative coupling of methyl ketones and primary or secondary amines to α-ketoamides has been developed. Four intermediates, α-iodoketone, α-aminoketone, iminium intermediate, and α-hydroxy amine have been identified through a series of control experiments. The atom-economic methodology can be scaled-up, tolerates a variety of functional groups, and is operationally simple.

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%。

The Pd(triNHC) complex was synthesized and used for the carbonylativecoupling of amine and aryliodide. The electron‐rich nature of palladium catalysts promoted the formation of α‐ketoamides with good yields and selectivity.
