Yy. Ku et al., AN EFFICIENT SYNTHESIS OF DES-N-METHYL-N-ACETYL ERYTHROMYCIN DERIVATIVES VIA THE N-OXIDE, Bioorganic & medicinal chemistry letters, 7(9), 1997, pp. 1203-1206
An efficient synthesis of des-N-methyl-N-acetyl erythromycin derivativ
es has been developed, it involves the Polonovsky reaction of erythrom
ycin N-oxide derivatives. The reaction conditions have been establishe
d so that the desired products can be prepared in high quality and in
good yields. This provides a convenient way to prepare des-N-methyl-N-
acetylerythromycin-based macrolides. (C) 1997 Elsevier Science Ltd.
