  Preparation and properties of 2-deoxyglycosyl isothiocyanates

  摘要：

  The syntheses of 3,4,6-tri-O-acetyl-2- deoxy-alpha and beta-D-arabino (D-lyxo)hexopyranosyl isothiocyanates (2, 3, 6, 7) and 4,6-di-O-acetyl-3-bromo-2,3-dideoxy-beta-D-arabinohexopyranosyl isothiocyanate (5) are reported. Treatments of 2,3,6, and 7 with phenacylamine hydrochloride and of 2 with aminoacetone hydrochloride gave the corresponding N-phenacyl (acetylmethyl)-N'-(2-deoxyglycosyl)-thioureas (8-12). The N-nucleoside analogues 5-methyl-1-(3',4',6'-tri-O- acetyl-2'-deoxy-alpha-D-arabinohexopyranosyl)-4-imidazoline-2-thione (13) was obtained by cyclodehydration of the thiourea 12.

  摘要3,4,6-三-O-乙酰基-2-脱氧-1-硫代-d-阿拉伯糖基六吡喃糖，2,4,6-三-O-乙酰基-3-脱氧-1-硫代-戊糖β-d-核糖-六吡喃糖，2,3,6-三-O-苯甲酰基-4-脱氧-1-硫代-β-d-木糖-六吡喃糖和2,3,4-三-O-乙酰基-6报道了-脱氧-1-硫代-β-d-吡喃葡萄糖。这些硫醇分别与苯基乙酰基羟肟基氯或吲哚-3-基乙酰基羟肟基氯偶联。硫酸化和随后的脱保护得到了葡糖营养素和葡糖溴素的相应脱氧衍生物，这是芥子油苷家族的两个主要代表。
