Title
(EN) PREPARATION METHOD OF VALIENAMINE USING SOLID CATALYSTS
(FR) PROCEDE DE PREPARATION DE VALIENAMINE AU MOYEN DE CATALYSEURS SOLIDES
Abstract
(EN) Disclosed is a preparation method of valienamine using solid catalysts. The valienamine, which has strong inhibiting activity, is prepared by selective hydrolysis of acarbose and acarbose derivatives, validamycin and validamycin derivatives, validamycin and validamycin derivatives, or validoxylamine and validoxylamine derivatives. In the present invention, a solid catalyst such as a strong acidic cation exchange resin, a strong basic anion exchange resin or zeolite is used.
(FR) La présente invention se rapporte à un procédé de préparation de valiénamine au moyen de catalyseurs solides. La valiénamine, qui possède une forte activité inhibitrice, est préparée par hydrolyse sélective d'acarbose et de dérivés d'acarbose, de validamycine et de dérivés de validamycine, ou de validoxylamine et de dérivés de validoxylamine. Dans le procédé de la présente invention, on utilise un catalyseur solide tel qu'une résine échangeuse de cations fortement acide, une résine échangeuse d'anions fortement basique ou de la zéolite.
