    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.

    摘要： A process for clarifying an alkoxylated product mixture produced using a calcium-based catalyst wherein the product mixture is heated to a temperature of from about 80.degree. C. to about 175.degree. C. to produce a filtration feed, the filtration feed being passed through a filter medium comprising material possessing polar groups to produce a clarified filtrate, the filtration feed being passed through the filter medium within about 5 days of being prepared, the filtration feed being passed through the filter medium until the desired degree of clarification is obtained, the temperature of the clarified filtrate being less than about 30.degree. C. but above the pour point of the clarified filtrate.

    摘要： The claimed invention provides a novel method of preparing 6-O-methyl erythromycin A. The process comprises the steps of reducing the 9-keto group of erythromycin A to form a 9-hydroxy erythromycin A, protecting the 9-, 2'-, and/or 4"-hydroxyl groups of erythromycin A, selectively methylating the 6-position of the 9-hydroxy erythromycin A derivative, deprotecting the hydroxyl groups and oxidizing the 9-hydroxyl to afford 6-O-methyl erythromycin A.
