Abstract
The present invention relates to a one-step process for preparing amido-carboxylic acid esters having the amide nitrogen positioned between two carbonyl carbons by reacting a carboxylic acid or carboxylic acid ester with a monohydric alcohol and either a lactam, amino-carboxylic acid or a polymeric amino-carboxylic acid. In this process, amidation, esterification, alcoholysis, and hydrolysis reactions occur simultaneously.
