A newdisaccharide block for OSW-1 natural steroidal antitumor agent was described. Regioisomeric 2- and 3-O-p-methoxybenzoyl derivatives of phenyl 1-thio-β-d-xylopyranoside and phenyl 2-O-acetyl-1-thio-β-l-arabinopyranoside derivatives blocked at positions 3 and 4 by R3Si groups were synthesized with a view to use them in the preparation of OSW-1 analogs modified at the disaccharide fragment.
描述了一种用于OSW-1天然类固醇抗肿瘤药的新型二糖阻滞剂。区域异构的2-和3- ö - p苯基甲氧基苯甲酰基衍生物1-硫代β- d -xylopyranOSide和苯基2- ö乙酰基-1-硫代β-升受阻于位置-arabinopyranOSide衍生物3和4由R 3合成Si基团是为了将它们用于制备在二糖片段上修饰的OSW-1类似物。
