The present invention is directed to novel biocatalytic processes for the conversion of aliphatic cc, w-dinitriles into the corresponding co- nitrilecarboxylic acid. More particularly, the present invention provides a method for the conversion of 1-cyanocyclohexaneacetonitrile to 1- cyanocyclohexaneacetic acid using an enzyme catalyst with nitrilase activity. 1~cyanocyclohexaneacetic acid is a useful intermediate in the synthesis of gabapentin.
La présente invention concerne de nouveaux procédés biocatalytiques permettant la conversion d'.alpha., .omega.-dinitriles aliphatiques en l'acide .omega.-nitrile carboxylique correspondant. Plus particulièrement, la présente invention concerne un procédé pour la conversion de 1-cyanocyclohexaneacétonitrile en acide 1-cyanocyclohexane acétique à l'aide d'un catalyseur enzymatique à activité nitrilase. L'acide 1-cyanocyclohexane acétique est un intermédiaire utile dans la synthèse de la gabapentine.
