Abstract
Process for the preparation of amides and esters, especially suitable for obtaining penicillins and cephalosporins, characterized in that a substituted N, N'-bis- (3-oxazolidinyl-2-one) phosphoricodiamide of the following formula *** (see formula 1) where X is a group selected from halogens and azido, preferably a chlorine atom, is reacted with the salt of a tertiary base, preferably triethylamine of a carboxylic acid, in an organic solvent in the presence of an amine or an alcohol, at temperatures between -5 and + 20ºC to obtain an amine or an ester.
