通过定向不对称吡嗪合成制备的头孢他汀7的20-和25 ' -外聚体,解决了外环的地形和稳定性问题,并揭示了该类抗肿瘤药物螺旋状(E/F, E ' /F ')环的生物活性中所起作用的氧羰基离子原理。
20- and 25‘-epimers of cephalostatin7, prepared by directed unsymmetrical pyrazine synthesis, address outer-ring topographical and stability questions and intimate an oxacarbenium ion rationale for the role in bioactivity of the spiroketal (E/F, E‘/F‘) rings of this class of antitumor agents.
