Process for the synthesis of alpha n alkylated amino acids and esters thereof, application to the synthesis of carboxyalkyl 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.
