L-aspartate) has been prepared by the polymerisation of α-benzyl β-N-succinimidyl L-aspartate and converted into poly-(β-L-aspartic acid) by hydrogenolysis; treatment of the poly(benzyl ester) with hydrogen bromide in acetic acid leads to a different polymer containing a substantial proportion of aspartimide residues. The analogous route cannot be used for the preparation of poly-(α-benzyl L-glutamate)

The preference for 5- over 6-membered rings in the intramolecular cyclisation of amines with diesters can be partially overcome with mixed methyl (or benzyl), tert-butyl diesters, and this effect is enhanced where there is a β-substituent. The hexalhydropyrimidines are formed enantiospecifically, the amount of racemization usually being less with a β-substituent present.
