A series of 3-(deacetoxymethyl)-1-oxa-1-dethiacephalosporins (1) bearing the 7-(alpha-alkoxyimono)acyl side chain were synthesized and their antibacterial properties were examined in comparison with that of FK-749 (2). (Z)-2-(Ethoxyimino)-2-(2 aminothiazol-4-yl)acetic acid was found to be a prefered side chain in the 1-oxa series, and the derivative 18b with this side chain proved to be a potential
合成了一系列带有7-(α-烷氧基亚基)酰基侧链的3-(脱乙酰氧基甲基)-1-氧杂-1-去脑头孢菌素(1),并与FK-749进行了比较(2)。 。在(oxox)系列中,发现(Z)-2-(乙氧基亚氨基)-2-(2氨基噻唑-4-基)乙酸是优选的侧链,具有该侧链的衍生物18b被证明是潜在的。广谱抗生素一点也不低于2。
