hydroxy derivative, whereas treatment of 3 with pyridine gave the 3,5-(cyclic sulfate). Dechlorosulfation of 7 afforded 5,6-dichloro-5,6-dideoxy-1,2-O-isopropylidene-β- l -idofuranose which, on acid hydrolysis, was converted into 3,6-anhydro-5-chloro-5-deoxy- l -idofuranose. 5-Chloro-5-deoxy-α- l -idofuranosidurono-6,3-lactone and 5-chloro-5-deoxy-β- l -idofuranurono-6,3-lactone derivatives were also
摘要1,2-O-异亚丙基-α-d-葡萄糖呋喃糖在0°和50°下与硫酰氯反应,得到6-氯-6-脱氧-1,2-O-异亚丙基-α-d-葡萄糖基呋喃糖3 1,5-双(氯硫酸盐)(3)和5,6-二氯-5,6-二脱氧-1,2-O-异亚丙基-β-1-异呋喃糖3-氯硫酸盐(7,未表征)。3的脱氯硫酸得到羟基衍生物,而吡啶处理3则得到3,5-(环硫酸盐)。7的脱硫得到5,6-二氯-5,6-二脱氧-1,2-O-异亚丙基-β-1-异呋喃糖,经酸水解后转化为3,6-脱水-5-氯-5-脱氧-1-氨基呋喃糖。还制备了5-氯-5-脱氧-α-1-偶氮呋喃并呋喃-6,3-内酯和5-氯-5-脱氧-β-1-基呋喃并呋喃-6,3-内酯衍生物。
