Based on the orchestrated application of PTC and Yu glycosylations, the first total synthesis of arylnaphthalide glycosides, phyllanthusmin D and 4''-O-acetylmananthoside B, which were claimed to be ideal antitumoral lead compounds in terms of cytotoxicity, cytotoxic selectivity, and novel working mechanism, were achieved. With easily accessible compounds as starting materials, the two target molecules
基于
PTC和Yu糖基化的协调应用,首次全合成芳基
萘苷、
叶黄素D和4''-O-乙酰
甘露糖苷B,这些化合物在细胞毒性、细胞毒性选择性和新颖性方面被认为是理想的抗肿瘤先导化合物工作机制,实现了。以易于获得的化合物为起始材料,以 9 步和 15 步的最长线性序列获得了两种目标分子,总产率分别为 29% 和 9%。通过合成研究,建立了有效且可扩展的合成叶木素的路线,并证实了芳基
萘苷中的阻转异构现象。
