    摘要： A process of producing atracurium besylate that substantially reduces the level of impurities in the final product and avoids the repeated use of ether is provided. In accordance with such a process, N, N'-4,10-dioxa-3,11-dioxotridecylene-1,13-bis-tetrahydropapaverine (Compound 1), methyl benzenesulfonate and a catalytic amount of an insoluble base in a solvent are combined to form a reaction mixture that is maintained for a period of time sufficient for atracurium besylate formation. The reaction mixture is then filtered to remove the insoluble base and the atracuriurn besylate is precipitated.

    摘要： A method for the preparation of D-chiro-inositol from kasugamycin, comprising the steps of: (a) reacting kasugamycin with an acetylating agent to form a crude hexa-acetate intermediate; (b) purifying the crude intermediate to form purified hexa-acetate intermediate; (c) deacetylating the purified intermediate to form D-chiro-inositol; and (d) isolating the D-chiro-inositol. The method permits efficient, large-scale preparation of D-chiro-inositol without the need for extensive chromatographic purification of the final D-chiro-inositol product.
