The present invention relates to a novel indolopyrrolocarbazole derivative which is represented by the formula [I]:
wherein:
A represents O, NH, or CH2;
R1 represents a single bond, a lower alkyl group, a lower alkenyl group, a lower alkynyl group, etc.;
R2 represents a phenyl group, a naphthyl group, or a five- or six-membered aromatic or aliphatic heterocyclic ring having at least one atom selected from N, S, or O, wherein the phenyl group, naphthyl group, aromatic or aliphatic heterocyclic ring may be substituted; and
G represents a hexose group or a pentose group, or a pharmaceutically acceptable salt thereof

Abstract Acyclic diastereoisomers, namely, 1-( N -acetyl-α-methylbenzylamino)-1-deoxyalditol acetates are readily obtained by reductive amination of aldoses with chiral α-methylbenzylamine (MBA) in the presence of sodium cyanoborohydride, and may be separated by reversed-phase 1.c. and, more effectively, by adsorption 1.c. According to this procedure, enantiomers of the common, neutral aldoses are

the most part at least without Walden inversions or other change, because hydrogenation of the sirupy product reduced it in more than 80% yield to crystalline methyl glucoside. The product from methyl-β-glucoside tetranitrate consisted of the 2,3,6-trinitrate (28%), the 3,6-dinitrate (17%), and an unidentified trinitrate (8%) which might have been a mixture.The structures of the first two compounds

Abstract Cellobiose, maltose, and 4- O -methyl- d -glucose were treated with 0.1–20m m 2-anthraquinonesulfonic acid in 0.1 m sodium hydroxide at 40°. The hydroxy carboxylic acids formed were separated by ion-exchange, and analyzed by g.l.c.-m.s. as their per(trimethylsilyl) derivatives. The acidic oxidation products of cellobiose were further fractionated into aldonic acids and carboxylaldoses by ion-exchange
摘要在0.1 m氢氧化钠中于40°C用0.1–20m m 2-蒽醌磺酸处理纤维二糖,麦芽糖和4-O-甲基-d-葡萄糖。通过离子交换分离形成的羟基羧酸,并通过glc-ms分析其全(三甲基甲硅烷基)衍生物。通过离子交换色谱将纤维二糖的酸性氧化产物进一步分馏为醛糖酸和羧醛糖。用硼氢化钠还原分离的羧基醛糖,然后在水解之前和之后通过glc-ms进行分析。糖的O-d-葡萄糖基和O-甲基取代的产物除了2-C-羧基戊糖外,还由赤藓酸,阿拉伯酸,核糖酸,葡糖酸和甘露酸组成。还原性d-葡萄糖单元的未取代产物为甲酸,乙醇酸,2-脱氧电子,
