The reaction of 3-cyano 5a, 3-diethylaminocarbonyl 5b, and 3-methoxycarbonylpyridine 5c with alkyllithiums 6 has been investigated as a method of preparing stable dihydropyridines. Reaction of 5a with 6 affords a mixture of 1,2- and 1,6-dihydropyridines 10 and 11, whereas reaction of 5b and 5c with 6 yields a mixture of 1,4- and 1,6-dihydropyridines 11 and 12. The cyano and diethylaminocarbonyl substituents
Compounds useful as protease inhibitors are provided, as are methods of use and preparation of such compounds and compositions containing such compounds. In one embodiment, the compounds are useful for inhibiting HIV protease enzymes, and are therefore useful in slowing the proliferation of HIV.
