Synthesis of clarithromycin ketolides chemically modified at the unreactive C10-methyl group

Autor: Kjell Undheim, Hany Fakhry Anwar, Mioara Andrei

Publikováno v: Bioorganicmedicinal chemistry. 25(8)

Chemoselective substitutions in the C10-methyl group of erythromycin A ketolides is reported. The C10-methyl group in the clarithromycin derived substrate 10,11-anhydro- O 6 -methyl-descladinosylerythromycin was activated by conversion into an allyl
