    inositols by blocking all but one hydroxyl group, converting the free hydroxyl group into its S -methyl dithiocarbonate, and treating it with tributylstannane. Suitable blocking-groups are methyl, benzyl, and methylthiomethyl ethers, and acetals. One cyclohexanepentol was prepared by the reductive deamination of an aminodeoxyinositol.

    The cyclohexenenones exo-and endo-2 were converted into the cyclohexenyl acetates exo-and endo-3 and exo-and endo-5 with a diastereoselectivity of >99: 1 (2 steps). Ether cleavage with DDQ in CH2Cl2/H2O (20: 1) and in situ ketal hydrolysis afforded the cyclohexenones 6 and 7 in up to 83% and 87% yield, respectively. Compound 6 was converted into (+)-allo- and (-)-proto-quercitol with a diastereoselectivity of 100: 0 (4 steps). Moreover, 6 was carried on to (-)-talo-quercitol whereas 7 furnished the four remaining title quercitols (3-5 steps) including both enantiomers of gala-quercitol.

    of analogues based on DCI were synthesised. These compounds were then evaluated for their ability to stimulate glucose transport using 3T3-L1 adipocytes as a model system. Positional analyses indicate that the hydroxyl group at position 1 is not essential for activity and can be modified without affecting glucose uptake. Removal of the hydroxyl at position 3 also had minimal effect on activity but
    d-手性肌醇(DCI,1)在糖尿病和胰岛素抵抗中具有治疗作用,但药代动力学不佳。为了研究DCI环己醇环上的哪些位置可能适合修饰以改善药物制剂,合成了一系列基于DCI的类似物。然后使用3T3-L1脂肪细胞作为模型系统评估这些化合物刺激葡萄糖转运的能力。位置分析表明,位置1上的羟基对于活性不是必需的,可以进行修饰而不会影响葡萄糖的摄取。除去3位上的羟基对活性也具有最小的影响,但是该基团对修饰敏感。相比之下,位置2的氧气对于DCI的效能至关重要,尽管该小组可以承受修改而不会从根本上影响活动。这些数据表明,DCI的环己醇环上的位置1和2提供了进一步的修饰范围,以开发具有所需药代动力学特征的DCI类似物,用于潜在地治疗代谢性疾病。
