Definitions

  • an acyl group is introduced in the N-3 position of the furoimidazole derivative.
  • the acylating reagents customary in the art such as, for example, the aliphatic or aromatic acid halides such as acetyl chloride, propionyl chloride or benzoyl chloride, the aliphatic or aromatic Carboxylic acid anhydrides such as acetic anhydride, the halogen formic acid esters such as chloroformic acid ethyl ester or ketene.
  • the acetic acid anhydiide which can act both as a reactant and as a solvent, has proven to be particularly suitable.

Abstract

L'invention a pour objet un nouveau procédé de fabrication de biotine (+) de formule (I), caractérisé en ce qu'un dérivé furo-imidazole de formule générale (II) est acylé en position 3 de N, le composé acylé est transformé, au moyen d'un donneur S, en un thiéno-imidazole, le groupe acyle est enlevé en position 3 de N, la chaîne latérale est introduite au moyen d'un réactif de Grignard et, après élimination du groupe hydroxy, hydrogénation du composé insaturé obtenu et séparation des groupes protecteurs en position 1 de N, on obtient le produit final biotine (+). La biotine (+) est une vitamine essentielle et est utilisée notamment dans le secteur pharmaceutique.
