The synthesis proceeds by alternative routes including the cyclic ketal amide route, the chiral carbamate amide route, and the chiral carbamate ester route. The compounds produced thereby are useful as thrombin receptor antagonists. The chemistry disclosed herein is exemplified in the following synthesis sequence:

The chemistry taught herein can be exemplified by the following scheme: n nwherein R 9 is selected from alkyl, aryl heteroaryl and arylalkyl groups having 1 to 10 carbon atoms, and R 11 is selected independently for each occurrence from alkyl, aryl heteroaryl and arylalkyl groups having 1 to 10 carbon atoms and hydrogen, X 2 is Cl, Br, or I; X 3 is selected from Cl and Br; and PdL n is a supported palladium metal catalyst or a soluble heterogeneous palladium catalyst. The L-derivatizing reagent is a moiety which converts the alcohol functional group of compound 137D to any leaving group which can be displaced by a triorgano-phosphite phosphonating agent.
