Abstract
The carboxyalkyl dipeptides are made by (a) reacting equiv. amounts of a carboxyalkyl amino acid or carboxyalkyl acid with 1,1-carbonyl diimidazole to give a new N-carboxyalkyl 2,5-oxazolidine dione of formula (I), (in which R1 is phenyl, R2 is carboethoxyl, R3 is H and is lower alkyl opt. with a protected amino gp.) and (b) reacting this anhydride, without isolation, with an amino acid opt. with the acid gp. protected.
