Abstract: In one aspect, the invention relates to a process for preparing 6-O-substituted erythromycin derivatives comprising reacting 2'-substituted and optionally 4''-substituted 9-oxime erythromycin derivatives with an alkylating agent in the presence of a palladium catalyst and phosphine. In another aspect, the invention relates to processes for preparing 6-O-substituted erythromycin ketolides using the palladium-catalyzed alkylation reaction.
