    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.
