Title (EN) SYNTHESIS OF ISOHEXIDE DICARBAMATES AND DERIVATIVES THEREOF
(FR) SYNTHÈSE DE DICARBAMATES D'ISOHEXIDE ET DÉRIVÉS DE CEUX-CI
Abstract:
(EN) Isohexide dicarbamates and a method of preparing the same are described. The method involves reacting a mixture of an isohexide and a cynate salt in a non-aqueous solvent, with a miscible acid having a pKa of about 3.7 or less. The isohexide dicarbamates can serve as precursor materials from which various derivative compounds can be synthesized.
(FR) L'invention concerne des dicarbamates d'isohexide et un procédé pour les préparer. Le procédé consiste à faire réagir un mélange d'un isohexide et d'un sel de cynate dans un solvant non aqueux, avec un acide miscible ayant un pKa égal ou inférieur à environ 3.7. Ces dicarbamates d'isohexide peuventt être utilisés en tant que matériaux précurseurs à partir desquels plusieurs composés dérivés peuvent être synthétisés.
