The present invention provides compounds that inhibit Factor XIa and methods of preventing or treating undesired thrombosis by administering a compound of the invention to a mammal. The invention also provides three-dimensional structures of Factor XIa and methods for designing or selecting additional Factor XIa inhibitors using these structures.
Synthesis of polysubstituted 3-hydroxypyridines via the revisited hetero-Diels–Alder reaction of 5-alkoxyoxazoles with dienophiles
A general and single-step access to polysubstituted 3-hydroxypyridine scaffolds via hetero-DielsâAlder (HDA) reactions between readily prepared 5-ethoxyoxazoles and dienophiles is reported. The HDA reaction, run in the presence of Nd(OTf)3 at room temperature, was successfully applied to various 5-ethoxyoxazoles showing good functional group tolerance, and led to a straightforward process to obtain useful building-blocks.
