Abstract 6- S -α- ( 2 ) and 6- S -β- d -glucopyranosyl-6-thiocyclomaltoheptaose ( 3 ) have been prepared by treatment of 6- O - p -tolylsulphonylcyclomaltoheptaose ( 1 ) with the sodium salts of 1-thio-α- and -β- d -glucopyranose, respectively, in 1,3-dimethyl- 2-oxohexahydropyrimidine. Compounds 2 and 3 , which were characterised by f.a.b.-m.s. and 1 H- and 13 C-n.m.r. spectroscopy, are more soluble
摘要用1-钠盐处理6-O-对甲苯磺酰基环麦芽庚糖(1),制备了6-S-α-(2)和6-S-β-d-吡喃葡萄糖基-6-硫代环麦芽七糖(3)。 1,3-二甲基-2-氧代六氢嘧啶中的硫代-α-和-β-d-吡喃葡萄糖。以fab-ms以及1 H-和13 Cn.mr光谱为特征的化合物2和3比环麦芽七糖更易溶于水,并通过包容增强疏水性化合物的溶解度。
