摘要 (S)-环氧氯丙烷和二苄胺经N-烃化所得(S)-N,N-二苄基-3-氯-2-羟基丙胺(4),与N-苄氧羰基-3-氟-4-吗啉基苯胺在碱性条件下缩合,得(S)-3-(3-氟-4-吗啉苯基)-5-[(N,N-二苄基)氨甲基]-1,3-噁唑烷-2-酮(6),再经催化氢解脱苄和乙酰化反应制得抗菌药利奈唑胺,总收率约57%(以二苄胺计)。 Linezolid was synthesized by N-alkylation from(S)-epichlorohydrin and dibenzylamine to give(S)-N,N-dibenzyl-3-chloro-2-hydroxypropyl amine(4),then condensation with N-carbobenzoxy-3-fluoro-4-morpholinoaniline to afford(S)-3-(3-fluoro-4-morpholinylphenyl)-5-[(N,N-dibenzyl)aminomethyl]-1,3-oxazolidin-2-one(6),which was subjected to debenzylation by hydrogenolysis and then acetylation with acetic anhydride.The overall yield was about 57%(based on dibenzylamine).
