Publication number: 20030144541Abstract: The invention concerns a method for preparing &agr;-halogenated ketones from secondary &agr;-halogenated alcohols. More particularly, the invention concerns the preparation of &agr;-trihalogenated ketones from secondary &agr;-trihalogenated alcohols. The method for preparing said &agr;-halogenated ketone is characterized in that it consists in oxidizing in liquid phase, a secondary &agr;-halogenated alcohol, using molecular oxygen or a gas containing same, in the presence of a catalyst based on a metal M1 selected among metals of group 1b and 8 of the periodic system of elements and optionally an activating element.Type: ApplicationFiled: November 4, 2002Publication date: July 31, 2003Inventor: Roland Jacquot

Patent number: RE38796Abstract: 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: GrantFiled: June 16, 2000Date of Patent: September 13, 2005Assignee: Ajinomoto Co.,Inc.Inventors: Yutaka Honda, Satoshi Katayama, Kunisuke Izawa, Masakazu Nakazawa, Takayuki Suzuki, Naoko Kanno
