An efficient method for the regioselective 3-O-silylation of beta-thiofucopyranoside was disclosed. Based on this discovery, we described a high-yielding strategy for the synthesis of the natural core structure Of L-fucan and its fully sulfated derivative. The bioassay suggested that octyl 2,3,4-tri-O-sulfo-alpha-L-fucopyranosyl-(I --> 3)-2,4-di-O-sulfo-alpha-L-fucopyranosyl-(I --> 3)-2,4-di-O-sul
公开了一种用于β-硫代呋喃呋喃核苷的区域选择性3-O-甲硅烷基化的有效方法。基于此发现,我们描述了合成L-富康及其完全硫酸化衍生物的天然核心结构的高产策略。生物测定表明,辛基2,3,4-三-O-磺基-α-L-呋喃二糖基-(I-> 3)-2,4-二-O-磺基-α-L-呋喃二糖基-(I- -> 3)-2,4-二-O-磺基-α-L-呋喃果糖基-(1-> 3)-2,4-二-O-磺基-β-L-呋喃果糖苷比其具有更好的抗肿瘤活性肉瘤180细胞和Lewis肺癌模型研究的游离四聚体的制备 (C)2004 Elsevier Ltd.保留所有权利。
