Number of biological substances and natural products are found to exist as enantiomeric pairs. In this instance, alvimopan 1 as shown in Fig. 1, has three chiral centers thus it will have theoretically eight diastereomers. Out of these, one of the diastereomers is found to be active as opioid antagonist and prescribed for the treatment of postoperative ileus. In order to establish the percentage content
发现许多生物物质和天然产物以对映体对形式存在。在这种情况下,如图1所示的alvimopan 1具有三个手性中心,因此理论上将具有8个非对映异构体。在这些化合物中,发现一种非对映异构体可作为阿片样物质拮抗剂发挥作用,并被指定用于术后肠梗阻的治疗。为了确定不需要的非对映异构体的百分比含量并定义迄今为止从未有过的原料药的规格,因此,我们尝试合成和表征所有可能的非对映异构体。在这里,我们介绍了我们的策略,由于在3个和4个手性碳原子中心处存在反相关关系,该策略已成功执行,从而获得了四种实际可行的非对映异构体。有趣的是,
