Esters and amides (including15N analogs) of 1-alkoxyaziridine-2,2-dicarboxylic acids that containN-alkoxy substituents (PriO, RO2CCH2O, (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 the1H NMR criteria, which were suggested for the determination of absolute configurations of diastereomers
包含 N-烷氧基取代基(PriO、RO2CCH2O、(R,S)-RO2CCH(Me)O 或 (S)-RO2CCH(Me)O)的 1-烷氧基
氮丙啶-2,2-二
羧酸的酯和酰胺(包括 15N 类似物) ) 合成。最后提到的类型的三酰胺以非对映异构纯形式分离。1 H NMR 标准的有效性,建议用于确定非对映异构体的绝对构型,已通过(S,S)-形式的 X 射线衍射研究证实。
