The X-ray crystal structures of
[(2′R,4′S)-3′-benzoyl-4′-
benzyl-5′-oxo-2′-phenyloxazolidin-4′-yl]acetic acid 16
and
[(2′S,4′R)-3′-acetyl-4′-
benzyl-5′-oxo-2′-phenyloxazolidin-4′-yl]acetic acid 19
have been determined and their conformations compared to those of
related oxazolidinones. Compounds of the type 16 and 19 have also been
shown to be useful precursors to succinimide-based peptidomimetics
possessing conformational restriction and latent reactivity.
以下化合物的X射线晶体结构已被确定,并将其构象与相关的噁唑烷酮进行了比较:
[(2′R,4′S)-3′-苯甲酰基-4′-苄基-5′-氧基-2′-苯基噁唑烷-4′-基]乙酸 16 以及
[(2′S,4′R)-3′-乙酰基-4′-苄基-5′-氧基-2′-苯基噁唑烷-4′-基]乙酸 19。
此类化合物16和19也已显示出其作为具有构象限制和潜在反应性的基于丁二酰亚胺的肽模拟物前体的实用性。
