  • FORMATION OF TETRA-SUBSTITUTED ENAMIDES AND STEREOSELECTIVE REDUCTION THEREOF
    Publication number: 20100041893
    Abstract: The present invention is directed to a practical process for the preparation of an enamide (II) by palladium catalyzed coupling of a primary amide (IV) with a compound of structural formula (III), as shown below: As well as to crystalline forms of a compound produced by this process, in particular, an anhydrous crystal form, Form B, and crystalline solvates falling into three patterns, Type 1, Type 2, and Type 3, and crystalline intermediate compounds produced in the process. Still further, the present invention relates to the stereoselective reduction of the tetrasubstituted enamide (II) to the corresponding amide (I).

  • Process for making 1,5-disubstituted imidazoles
    Patent number: 6140508
    Abstract: The present invention is directed to a process for synthesizing 1,5-disubstituted imidazoles, which are useful in the preparation of farnesyl-protein transferase inhibitors.
    Type: Grant
    Filed: June 23, 1999
    Date of Patent: October 31, 2000

  • Tandem asymmetric transformation process
    Patent number: 5977371
    Abstract: The instant invention provides a homologation process for making a zincate homoenolate from a carbon bound enolate zincate, by treating the carbon bound enolate zincate with an alkoxy lithium reagent. The homologation step can be coupled with a homoaldol reaction, as well as with other transmetallation reactions, in a one pot process. The zincate homoenolate is a useful intermediate in the preparation of a variety of different end-products, such as HIV protease inhibitors and renin inhibitors.
