  • Patent number: 6844299
    Abstract: This invention generally relates to new polyol ester derivatives of polyamines for use as dispersant additives compatible in synthetic ester-based turbo oils. The dispersant additives of the present invention consist of a hydrocarbon acid, a polyol, an amine carrier such as diacid or cyclic anhydride and a polyamine. The hydrocarbon acid makes up the non-polar hydrocarbon portion of the dispersant and the polyamine functions as the polar headgroup. The diacid or cyclic anhydride provides a means for attaching the polar polyamine to the dispersant structure through an amide linkage. Different dispersant structures are obtained by varying the hydrocarbon acid, the polyol and the nature of the polyamine.

  • Patent number: 6469199
    Abstract: New secondary amines are described which are prepared from inexpensive, commercially available raw materials, are stable at room temperature, and are reactive toward electrophiles. The secondary amines are prepared by the addition of one or more primary amines with one or more male (amide/ester) and fumar (amide/ester) Michael receptors. The above amines can be used as coreactants with aliphatic polyisocyanates for polyurea coatings. The novel secondary amines are also described as particularly useful as part of a two-part liquid pavement marking composition for pavement markings.

  • Patent number: 6451854
    Abstract: The present invention relates to &agr;-amino acid phenyl ester derivatives having general formula (I) wherein R1 is (C1-3)alkyloxy; R2 is (C1-3)alkyl, (C1-3)alkyloxy or (C2-3)alkenyl; R3 is hydrogen, (C1-3)alkyl, (C1-3)alkyloxy or (C2-3)alkenyl; R4 is (C1-6)alkyl; R5 and R6 are independently (C1-6)alkyl, (C2-6)alkenyl, (C2-6)alkynyl or aralkyl, each of which may be optionally substituted with (C1-3)alkyloxy, (C1-3)alkyloxycarbonyl, cyano or NR7R8; R7 and R8 are independently (C1-6)alkyl; or a pharmaceutically acceptable salt thereof. The invention also relates to pharmaceutical compositions comprising said derivatives, and to the use of these &agr;-amino acid phenyl ester derivatives as hypnotics for the induction and maintenance of general anaesthesia.

  • Patent number: 6420592
    Abstract: Phosphonamide compounds and methods of forming those compounds are provided. The inventive methods comprise forming a template opened-ring phosphonamide compound and optionally subjecting the template to a ring-closing metathesis reaction in the presence of a ring-closing catalyst (e.g., a Grubbs catalyst) to yield a heterocyclic phosphonamide. Advantageously, the template structures can be provided with a wide array of functional groups (e.g., amino acid side chains, peptides) chosen to provide particular properties to the compound.

  • Publication number: 20020042537
    Abstract: The present invention provides a method for industrially producing an optically active lysine derivative useful as a pharmaceutical intermediate. More particularly, the present invention provides a production method including protecting an amino group or an amino group and carboxyl group of optically active 2-amino-6-methyl-6-nitroheptanoic acid with a protecting group, reducing a nitro group to synthesize a 6,6-dimethyl lysine derivative and reacting the 6,6-dimethyl lysine derivative with an acetic acid derivative.
