    Practical chemical and enzymatic technologies for (S)-1,4-benzodioxan-2-carboxypiperizine intermediate in the synthesis of (S)-doxazosin mesylate
    摘要:
    (S)-1,4-Benzodioxan-2-carboxypiperazine (S)-2, the key chiral intermediate for the synthesis of (S)-doxazosin, was prepared utilizing two approaches: (i) enzymatic resolution of ethyl 1,4-benzodioxan-2-carboxylate with an esterase (Serratia) followed by an-de formation; (ii) direct resolution of 1,4-benzodioxan-2-carboxypiperazine 2 with D-tartaric acid. An efficient process for the conversion of (S)-2 to (S)-doxazosin mesylate was developed (80% yield, 99.9% e.e.). (C) 2001 Elsevier Science Ltd. All rights reserved.

    [EN] The present invention relates to a process for the preparation of chiral 2-hydroxymethyl-l,4-benzodioxane compound. The method in accordance with the present invention comprises the steps of reacting chiral epihalohydrin or chiral glycidyl sulfonate with catechol or its derivative in a presence of a tertiary organic amine or its ammonium salt to carry out an ring opening reaction of the epoxide compound and treating the ring-opened product with an inorganic base to carry out a cyclization reaction of the ring-opened product to prepare the targeted 2-hydroxymethyl-l,4-benzodioxane. The method of the present invention provides the chiral 2-hydroxymethyl-l,4-benzodioxane compound in high optical purity and with improved yield due to reduced side reactions.
    [FR] L'invention concerne un procédé de préparation d'un composé chiral de 2-hydroxyméthyl-1,4-benzodioxane. Ce procédé consiste à effectuer la réaction d'épihalohydrine chirale ou de sulfonate de glycidyle chiral avec catéchol ou son dérivé en présence d'une amine organique tertiaire ou de son sel ammonium afin d'opérer une réaction d'ouverture de chaîne du composé époxyde et à traiter le produit à chaîne ouverte avec une base inorganique afin d'effectuer une réaction de cyclisation dudit produit, de manière à préparer le 2-hydroxyméthyl-1,4-benzodioxane ciblé. Ce procédé permet d'obtenir un composé chiral de 2-hydroxyméthyl-1,4-benzodioxane très pur sur le plan optique et en quantités accrues dues à la diminution des réactions secondaires.
