A novel series of 11,12-benzoxazine ketolide derivatives of erythromycin A has been synthesized. The C11,C12-benzoxazine structure was constructed stereoselectively through an intramolecular Michael addition of a C12-O-(2-aminophenyl) group to the enone functionality of the 10,11-anhydro erythromycin A derivative 3.
已经合成了一系列新的红霉素A的11,12-苯并恶嗪酮化物衍生物。通过分子内迈克尔将C12- O-(2-氨基苯基)基团加到10,11-脱水红霉素A衍生物3的烯酮官能团上,立体选择性地构建了C11,C12-苯并恶嗪结构。
