Av. Prosyanik et al., ASYMMETRIC NITROGEN - 80 - DIASTEREOMERIC DERIVATIVES OF 1-ALKOXYAZIRIDINE-2,2-DICARBOXYLIC ACIDS - SYNTHESIS, STRUCTURE, AND ABSOLUTE-CONFIGURATION, Russian chemical bulletin, 47(1), 1998, pp. 119-126
Esters and amides (including N-15 analogs) of 1-alkoxyaziridine-2,2-di
carboxylic acids that contain N-alkoxy substituents ((PrO)-O-i, RO2CCH
2O, (R,S)-RO2CCH(Me)O, or (S)-RO2CCH(Me)O) were synthesized. Triamide
of the last-mentioned type was isolated in the diastereomerically pure
forms. The validity of the H-1 NMR criteria, which were suggested for
the determination of absolute configurations of diastereomers, was co
nfirmed by X-ray diffraction study of the (S,S)-form.
