protection of methyl α-D-glucopyranoside and subsequent catalytic Ferrier rearrangement to a deoxyinosose. Thus, methyl α-D-glucopyranoside was converted by an improved procedure into methyl 4,6-O-benzylidene-α-D-glucopyranoside 4 and thence into methyl 3-O-benzoyl-2-O-benzyl-4,6-O-benzylidene-α-D-glucopyranoside 7 without recourse to column chromatography. Compound 7 was converted into methyl 3,4-di-O
一种新的路由,结构改性d -肌醇肌醇1,3,4,5-四磷酸盐类似物,d -2-脱氧肌肌醇1,3,4,5-四磷酸盐3,描述,涉及作为关键步骤是对甲基α- D-吡喃葡萄糖苷进行选择性保护,随后催化Ferrier重排为脱氧肌苷。因此,甲基α- d吡喃葡萄糖苷被转化通过改进的过程成甲基4,6- ø -亚苄基- α- d吡喃葡萄糖苷4,然后进入3- ø -苯甲酰基-2- ø -苄基-4,6- O-亚苄基-α- D-吡喃葡萄糖苷7,无需柱色谱法。化合物7转化成甲基3,4-二- ø -苯甲酰基-2- ö苄基-6-脱氧α- d -木糖-己-5-烯吡喃糖苷12经由甲基3,4-二- ö -benzoyl- 2 - O-苄基-6-溴-6-脱氧-α- D-吡喃葡萄糖苷8.用三氟乙酸汞(II)重整烯醇醚12 (2 S,3 R,4 S,5 R)-2,3 -二苯甲酰氧基-4-苄氧基-5-羟基环己酮13和(2 S,3 R,4
