Abstract
Stereoselective process for the industrial synthesis of compounds of formula (I): ##STR1## where R.sub.1 is linear or branched lower alkyl with 1 to 6 carbon atoms, PA0 R.sub.2 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.
