see text] Stereoselective total synthesis of scytophycin C, a marine 22-membered macrolide displaying potent activity against a variety of human carcinoma cell lines, has been reported in which the polypropionate structure bearing contiguous asymmetric centers was stereospecifically constructed by using new acyclic stereocontrol. This paper describes stereoselective syntheses of the C(1)-C(18) segment
[结构:见正文]已有报道,细胞藻素C的立体选择性全合成是一种海洋22元大环内酯类化合物,对多种人类癌细胞系均显示出强效活性,其中通过使用新的无环化合物立体定向地构建了具有连续不对称中心的聚丙烯酸酯结构。立体声控制。本文介绍了立体选择性合成的C(1)-C(18)节(段A),包括一个反式-双取代的二氢吡喃环和C(19)-C(31)节(段B)具有八个立体生成的中心。
