Synthetic Studies on Erythromycin Derivatives: Reactivity of the C12-21 Alkene
Molecules, 2006 The reactivity of the C12-21 alkene of some erythromycin A derivatives was studied. This double bond was easily oxidized to the corresponding epoxide with excellent stereoselectivity. A single crystal X-ray structure showed that the epoxide moiety was on
