A short synthetic approach to the protected uracil 3′-epi-polyoxin C 20 has been developed. The stereoselective [3,3]-sigmatropic rearrangement of the corresponding 7-thiocyanato-α-d-xylo-hept-5-enfuranose 6 was employed as the key step to construct the C-5 stereocentre in 5-isothiocyanato-α-d-gluco-hept-6-enfuranose 8 and the formal synthesis of uracil 3′-epi-polyoxin C has been accomplished for the
已经开发了一种用于保护的尿嘧啶3'-表-多聚氧还蛋白C 20的短合成方法。相应的7-硫氰酸根-α-d-二甲苯基-庚5-呋喃糖6的立体选择性[3,3]-σ重排被用作构建5-异硫氰酸根-α-d中C-5立体中心的关键步骤-葡萄糖-庚基-6-呋喃糖8和尿嘧啶3'-表-多聚毒素C的正式合成是首次完成。这种合成提供了一种简便的方法来制备多克级的水垢,因此对于研究多毒素的结构与活性之间的关系以及寻找更有效和有效的抗候选人剂很有用。
