Asymmetric syntheses of two of GlaxoSmithKline's highly potent phosphodiesterase IV inhibitors CMPI 1 and CMPO 2 have been accomplished from nitroethane and simple precursors in 8 and 7 steps, respectively. The suggested synthetic strategy involves as a key stage the silylation of enantiopure six-membered cyclic nitronates. In vitro studies of PDE IVB1 inhibition revealed a significant difference in the activity of CMPI 1 and CMPO 2 enantiomers.
葛兰素史克的两种高效磷酸二酯酶 IV 抑制剂 CMPI 1 和 CMPO 2 已分别通过 8 步和 7 步从硝基乙烷和简单前体完成不对称合成。建议的合成策略包括对映体纯六元环硝基化合物的硅烷化作为关键阶段。 PDE IVB1 抑制的体外研究表明 CMPI 1 和 CMPO 2 对映体的活性存在显着差异。
