The present invention relates to bicyclic himbacine derivatives of the formula (structurally represented) or a pharmaceutically acceptable salt thereof wherein: R1 is -[C(Ra)(Rb)]x-[C(Rb)(Rb)]y-C(0)NH2, or -N(H)-[(CH2)]zC(0)-NH2; W is any of the recited compounds and the remaining variables are described herein. The compounds of the invention are effective inhibitors of the PAR -1 receptor. The inventive compounds may be used for the treatment or prophylaxis of disease states such as ASC, secondary prevention of myocardial infarction or stroke, or PAD.
synthesis of γ-hydroxybutenolides. The carbonyl group in butenolide holds the position of thiophenyl moiety in reacting furans. Decomposition of the initially formed [4 + 2] endoperoxide into products through a radical chain mechanism is proposed, as the fate of thiophenyl moiety is its transformation into ethyl phenylsulfenate (PhS-OEt) and diphenyldisulfide. Under the reaction conditions, the sulfenate is
