Unprecedented tandem allylic alkylation/intermolecular Michael addition was used in the preparation of novel bicyclic azalides. NMR spectroscopy was used not only to unambiguously determine and characterize the structures of these unexpected products of chemical reaction but also to investigate the effect the rigid bicyclic modification has on the conformation of the whole molecule. Thus, some of the
前所未有的串联烯丙基烷基化/分子间迈克尔加成用于制备新型双环氮杂内酯。核磁共振波谱不仅用于明确确定和表征这些意想不到的化学反应产物的结构,还用于研究刚性双环修饰对整个分子构象的影响。因此,制备的一些大环内酯类在众所周知的抗生素药物阿奇霉素范围内显示出抗菌活性。
