4(II)- and 6(II)-sulfate, and the 6(I),6(II)-disulfate derivatives, is reported for the first time. These molecules will be useful for the study of the early steps of the biosynthesis and sorting of proteoglycans. All target compounds were readily obtained from the common key intermediate 4-methoxyphenyl O-(2,3-di-O-benzoyl-4,6-di-O-levulinoyl-beta-D-galactopyranosyl)-(1-->3)-2-O-benzoyl-4,6-O-benzylide
快速制备二糖4-甲氧基苯基O-(β-D-吡喃半乳糖基)-(1-> 3)-β-D-吡喃半乳糖苷的各种磺化物形式的硫酸盐,即4(I)-和6(I)-硫酸盐首次报道了4(II)-和6(II)-硫酸盐和6(I),6(II)-二硫酸盐衍生物。这些分子将用于研究蛋白聚糖的生物合成和分选的早期步骤。所有目标化合物均易于从常见的关键中间体4-甲氧基苯基O-(2,3-二-O-苯甲酰基-4,6-二-O-乙酰丙酰基-β-D-吡喃半乳糖基)-(1-> 3 )-2-O-苯甲酰基-4,6-O-亚苄基-β-D-吡喃半乳糖苷,可以容易地由常见的起始原料4-甲氧基苯基4,6-O-亚苄基-β-D-吡喃半乳糖苷制备。
