This article describes a simple method for the synthesis of roxifiban, a potent glycoprotein GP IIb-IIIa receptor antagonist, by a diastereoselective coupling approach to give >99.9% optical purity. We have also described an attempt to resolve the key syn

Using isoxazoline XR299 (la) as a starting point for the design of highly potent, long-duration GPIIb/IIIa antagonists, the effect of placing lipophilic substituents at positions α and β to the carboxylate moiety was evaluated. Of the compounds studied, it was found that the n-butyl carbamate 24u1,2 exhibited superior potency and duration of ex vivo antiplatelet effects in dogs. Replacement of the benzamidin-4-yl moiety with alternative basic groups, elimination of the isoxazoline stereocenter, and reversal of the orientation of the isoxazoline ring resulted in lowered potency and/or duration of action.
