product with significant anti-cancer activity. A derivative (4) of D-glucal is converted to a model compound (10) for the lower periphery of the maytansinoid ring via alkylation at C-6 using an allylic sulfide anion, followed by oxidation to the sulfoxide and [2,3]-sigmatropic rearrangement to the sulfenate ester. In addition, a method is disclosed for conversion of D-arabinose to a chiron (18) for a portion
摘要美登素(1)是一种具有显着抗癌活性的大环天然产物。通过使用烯丙基硫醚阴离子在C-6处烷基化,将D-葡萄糖的衍生物(4)转化为美登木素生物碱环下周边的模型化合物(10),然后氧化为亚砜和[2,3] -亚磺酸酯的-σ重排。另外,公开了一种方法,用于将美登木素生物碱类的上周边的一部分从D-阿拉伯糖转化为Chiron(18)。
