phosphodiesterase IV (PDE IV) inhibitor rolipram (1) provided (-)-1, and this enantiomer was converted into its 1-(4-bromobenzyl) derivative, (+)-2. X-ray structural analysis of (+)-2 established the absolute configuration as R, which provides the first direct evidence for a previously assumed assignment of configuration. The crystal structure of (+)-2 and the PDE inhibitory activity of both enantiomers
磷酸二酯酶IV(PDE IV)抑制剂rolipram(1)的手性HPLC拆分提供了(-)-1,并将该对映异构体转换为其1-(4-溴苄基)衍生物(+)-2。(+)-2的X射线结构分析将绝对构型确定为R,这为先前假定的构型分配提供了第一个直接证据。(2)的两个对映异构体的(+)-2的晶体结构和PDE抑制活性在先前提出的拓扑模型的背景下进行了讨论。
