The tetradeuterated analogues of (R)- and (S)-ifosfamide [(S)- and (R)-2-(2-chloro-2,2-dideuterioethyl)amino-3-(2-chloroethyl)-6,6-dideuterio-tetrahydro-2H-1,3,2-oxazaphosphorin-2-oxide, (S)- and (R)-1-d4] were synthesized by modification of a literature procedure. The enantiomers of α-methylbenzylamine were employed as the resolving agents in the multi-step synthesis in a 9% overall yield. The selected
(R)-和(S)-异环磷酰胺[(S)-和(R)-2-(2-氯-2,2-二氘代乙基)氨基-3-(2-氯乙基)-6,6的四氘代类似物-dideuterio-tetrahydro-2H-1,3,2-oxazaphosphorin-2-oxide, (S)- 和 (R)-1-d4] 通过修改文献程序合成。α-甲基苄胺的对映异构体被用作多步合成中的拆分剂,总产率为 9%。选定的标记位置应最小化潜在同位素效应,有助于通过假外消旋体方法研究异环磷酰胺的立体选择性代谢
