A de novo approach to the synthesis of glycosylated methymycin analogues with structural and stereochemical diversity.
A divergent and highly stereoselective route to 11 glycosylated methymycin analogues has been developed. The key to the success of this method was the iterative use of the Pd-catalyzed glycosylation reaction and postglycosylation transformation. This unique application of Pd-catalyzed glycosylation demonstrates the breath of α/β- and d/l-glycosylation of macrolides that can be efficiently prepared using a de novo asymmetric approach to the carbohydrate portion.
