    Abstract: Disclosed are a novel process for preparing D-alloisoleucine and an improved process for epimerizing L-isoleucine to prepare D-alloisoleucine. In the former process, (2S, 3S)-tartaric acid derivative of formula I below; wherein R stands for a hydrogen atom, a C1-C3 lower alkyl group, lower alkoxy group, chlorine atom, bromine atom and nitro group; and “n” is a number of 0, 1 and 2; is combined with an epimer mixture of L-isoleucine and D-alloisoleucine in a reaction medium to form a complex of D-alloisoleucine and the compound of formula I. The precipitated complex is decomposed by putting it in an alcohol to isolate D-alloisoleucine. In the latter process, L-isoleucine is suspended in an inert solvent which does not substantially dissolve amino acids, and epimerized in the presence of C1-C5 saturated lower fatty acid and salicylaldehyde.

  • Patent number: 6281176
    Abstract: This invention provides a process for producing a betaine/amine oxide mixture. This process comprises reacting, in a liquid medium, an alkali metal &ohgr;-halocarboxylate with a first tertiary amine of the formula Ra2RbN, wherein each Ra group is a hydrocarbyl group which independently has from 1 to about 4 carbon atoms, and wherein the Rb group is a hydrocarbyl group which has from about 8 to about 24 carbon atoms, to produce a betaine product solution. To the betaine product solution is added a second tertiary amine of the formula Ra2RbN, wherein each Ra group is a hydrocarbyl group which independently has from 1 to about 4 carbon atoms, and wherein the Rb group is a hydrocarbyl group which has from about 8 to about 24 carbon atoms, to produce an amine/betaine mixture. The first and second tertiary amines can be separate portions of the same amine. Preferably, however, the first and second tertiary amines differ from each other.

  • Patent number: 6153753
    Abstract: Process for the preparation of an N-acyl amino carboxylic acid by means of a carboxymethylation reaction. In this reaction, a reaction mixture is formed which contains a base pair, carbon monoxide, hydrogen and an aldehyde with the base pair comprising a carbamoyl compound and a carboxymethylation catalyst precursor. In a preferred embodiment, the carbamoyl compound and aldehyde are selected to yield an N-acyl amino carboxylic acid which is readily converted to N-(phosphonomethyl)glycine, or a salt or ester thereof.
