Himbacine derived thrombin receptor antagonists: Discovery of a new tricyclic core
摘要:
The synthesis and biological activity of a novel series of thrombin receptor antagonists is described. This series of compounds showed excellent in vitro and in vivo potency. The most potent compound 40 had an IC50 of 7.6 nM and showed robust inhibition of platelet aggregation in a cynomolgus monkey model after oral administration. (c) 2007 Elsevier Ltd.

A single batch process for preparing (R)-benzyl-4-hydroxy-2-pentynoate by reacting (R)-3-butyn-2-ol with 1,1,1,3,3,3-hexamethyldisilazane to silylate the starting alcohol, followed by deprotonation with an alkyl lithium compound, then a reaction with a haloformate compound, and finally a hydrolysis reaction to arrive at the product ester.
