  • Process for producing 3-amino-2-oxo-1-halogenopropane derivatives
    Patent number: 5902887
    Abstract: Compounds formed by reacting a protected amino acid with an alkali metal enolate of an alkyl acetate are reacted with a halogenating agent for halogenation of the 2-position, or a protected amino acid is reacted with an alkali metal enolate of an alkyl halogenoacetate, to form a 4-amino-3-oxo-2-halogenobutanoic acid ester derivative, and hydrolysis and decarboxylation are conducted to produce a 3-amino-2-oxo-1-halogenopropane derivative or its salt. The present method is a useful process for producing a 3-amino-2-oxo-1-halogenopropane derivatives which can easily be converted to a 3-amino-1,2-epoxypropane.
    Type: Grant
    Filed: April 14, 1998
    Date of Patent: May 11, 1999
    Assignee: Ajinomoto Co., Inc.
    Inventors: Yutaka Honda, Satoshi Katayama, Kunisuke Izawa, Masakazu Nakazawa, Takayuki Suzuki, Naoko Kanno

  • Granular feed additives for ruminants containing lipase, bile powder and pancreatin
    Patent number: 5753223
    Abstract: The invention relates to biologically active substances coated with a coating composition containing at least one substance selected from the group consisting of hardened vegetable fats and oils, hardened animal fats and oils, fatty acid esters and phospholipids and an enzyme and/or enzyme activator where the outermost surface portion of the coating layer contains substantially no enzyme and/or enzyme activator. The invention materials exhibit excellent protection in the rumen of ruminant animals and allow for the dissolution in the post-abomasum lower digestive organs of the ruminant.
