Syntheses d'amidoesters par reaction de Kolbe

Abderrahman, Ben Moufida,Laurent, Eliane,Marquet, Bernard

, p. 571 - 578 (2007/10/02)

The synthesis of amidoesters has been investigated by anodic cooxidation of diacid hemiesters CO2H-CH2-Z-CO2CH3 -CH2-> and amidoacids R1-N(Y)-(CH2)2-CO2H .The scope of this reaction was examined in detail.This synthetic pathway provided very a simple access to a wide range of amidoesters R1-N(Y)-(CH2)3-Z-CO2CH3 by varying Z and R1 as well as n value.
