Abstract

L'invention concerne un procédé de préparation d'acide 2-cétogulonique. Le procédé de l'invention consiste à réduire en acide 2-cétogulonique l'acide 2,5-dicétogluconique, ses esters alkyliques ou ses sels par l'action d'un aminoborane. L'acide 2-cétogulonique est un composé intermédiaire pour la production de l'acide ascorbique.
