Abstract

Conversion of the easily available trans-2-oxoimidazolidine-4-carboxylic acid 1 to the corresponding imidazolidines 8 gives after one-step oxidation and ring cleavage the diamino acid 2 in high yield. The difference in the trans-vicinal couplings for the hydrogen-bonded and nonbonded compounds suggests different ring geometry as a result of the balancing effect of the N1 substituent on the "allylic strain".
