  • Publication number: 20080269499
    Abstract: A process is provided for preparing spiro-hydantoin compounds of the formula II wherein Z is N or CR4b; K and L are independently O or S; Ar is an optionally substituted aryl or heteroaryl; A2 is a linker, G? is a linker; Q is a linker; and R2, R4a, R4c, and Rh are defined in the specification. The process optionally includes the enantiomeric separation of intermediates to allow preparation of enantiomers of the spiro-hydantoin compounds of formula II. Substituted spiro-hydantoin compounds may be prepared from the spiro-hydantoin compounds of formula II. The spiro-hydantoin compound of formula II and the substituted spiro-hydantoin compounds are useful in the treatment of immune or inflammatory diseases. Also, provided are products made by the instant inventive process and crystalline forms (prepared by any process) of the substituted spiro-hydantoin compound, 5-[(5S,9R)-9-(4-Cyanophenyl)-3-(3,5-dichlorophenyl)-1-methyl-2,4-dioxo-1,3,7-triazaspiro[4.

  • Patent number: 6835841
    Abstract: A novel process for the asymmetric synthesis of substituted cyclic &bgr;-amino-carboxylates of the type shown in the specification from appropriate &bgr;-enamino-ester starting materials is described. These compounds are useful as intermediates for MMP and TACE inhibitors.

  • Patent number: 4673900
    Abstract: The invention provides a novel attachment for a discoid capacitor and the like to the inside of a tubular casing and to a central lead. An electrically insulating sealing element is positioned below the capacitor during assembly vertically into the casing. The element fits closely about the lead and is deformed into contact with the wall of the housing about the capacitor. The element thus forms a dam to contain solder and flux used to couple the capacitor to the lead and to the casing from above the capacitor so that the solder and flux cannot pass by the capacitor into undesirable locations below the capacitor.
