长期以来,在世界范围内对青霉素6位氨基衍生物已作过极为广泛的研究,但对6位腙(或肼)的衍生物却做得极少,至于在6-腙(或肼)青霉素上引入6α-甲氧基的工作,更未见报道。我们在合成6α-甲氧基-6β-
For a long time, penicillin 6-amino derivatives have been extensively studied worldwide, but derivatives of 6-hydrazone (or hydrazine) have been made very little. As for the 6-hydrazone (or hydrazine) The introduction of 6α-methoxy on the work has not been reported. We are in the synthesis of 6α-methoxy-6β-
