Significance

Derivatization of erythromycin A led to the formation of azithromycin which is active against a broader range of bacteria, and has greater acid stability and increased oral bioavailability compared with the erythromycins. This ­synthesis stems from the desymmetrization of 2-substituted glycerols to construct the two quaternary stereocenters of azithromycin.
