PROCEED FROM SYNTHESE D'ALPHA AMINO ACIDES N ALKYKES ET DE LEURS ESTERS APPLICATION TO THE SYNTHESE OF CARBOXYLALKYL DIPEPTIDES

摘要

Stereoselective process for the industrial synthesis of compounds of formula (I): IMAGE (I) where R1 is linear or branched lower alkyl with 1 to 6 carbon atoms, R2 is a linear or branched lower alkyl with 1 to 4 carbon atoms, employing inexpensive starting materials and obtaining optimum yields. Application to the synthesis of carboxyalkyl dipeptides.
