new bolaamphiphile carbohydrate derivatives having general structures AO(CH 2 ) n OB or [AO(CH 2 ) n ] 2 C(OH)R. The hydrophilic heads A and B (identical or different) are d -glucose, d -galactose, xylitol, or their respective protected derivatives, and R is an alkyl chain. The carbohydrate units A and B are condensed in the first step as di- O -isopropylidene derivatives with either α,ω-dibromo-
摘要我们合成了具有结构AstructuresO(CH 2)nOB或[AO(CH 2)n] 2 C(OH)R的新型保兰两亲碳水化合物衍生物。亲水性头A和B(相同或不同)是d-葡萄糖,d-半乳糖,木糖醇或其各自的被保护的衍生物,并且R是烷基链。在第一步中,在9:1或4:1甲苯-Me 2 SO的粉末状KOH存在下,将碳水化合物单元A和B作为二-O-异亚丙基衍生物与α,ω-二溴-或二甲基-烷烃进行缩合。或者选择性或缩醛基团的总脱保护和任一区域选择性酯化或醚化区域特异性的适当选择允许使用的亲水或这些新表面活性剂的亲脂性质的调节。
