Abstract
The title glycouril 1 was spontaneously resolved into enantiomers by crystallisation from H2O and sorting of conglomerate crystals, then N-chlorination and N-aminomethylation to give 2, 3 and 4, respectively, were studied. The absolute configuration 1R,5R-(+) was determined by an X-ray diffraction study of diastereomeric N,N-bis-aminomethyl derivative (−)-4.
