  Two-step conversions of myo-inositol into (±)-2,3,4,5,6- and 1,3,4,5,6-penta-O-benzyl-myo-inositols are described. Starting from these monohydroxy derivatives of myo-inositol, O-β-L-arabinopyranosyl-(1 → 2)-sn-myo-inositol from Japanese green tea [SENCHA], Camellia sinensis, and O-α-D-galactopyranosyl-(1 → 3)-sn-myo-inositol (galactinol) as well as its homolog, O-α-D-galactopyranosyl-(1 → 6II)-galactinol, were synthesized by way of the in situ activating glycosylation procedure.

  one hydroxyl group via their alkali metal alkoxides (sodium or lithium) preferentially occurs at a hydroxyl group having a vicinal cis-oxygen atom. In general the observed selectivity is relatively higher for lithium alkoxides than for the corresponding sodium alkoxide. The observed regioselectivity is also dependent on other factors such as the solvent and reaction temperature. A perusal of the results

  含有一个以上羟基的肌醇衍生物经由其碱金属醇盐（钠或锂）的O-烷基化优先发生在具有邻位顺式氧原子的羟基上。通常，观察到的对于烷氧基锂的选择性比对相应的烷氧基钠的选择性更高。观察到的区域选择性还取决于其他因素，例如溶剂和反应温度。对本文提供的结果以及文献中提供的结果的仔细研究表明，肌醇衍生物对金属离子的螯合在观察到的区域选择性中起着重要作用。与反应的羟基的轴向或赤道位置有关的立体因素对这些O-烷基化反应的结果没有太大贡献。
• An Effective Strategy for the Synthesis of 6-O-(2-Amino-2-deoxy-.alpha.-D-glucopyranosyl)-D-chiro- and -D-myo-inositol 1-Phosphate Related to Putative Insulin Mimetics

  Two glycosylinositol phosphates related to putative insulin mimetics, 6-O-(2-amino-2-deoxy-alpha-D-glucopyranosyl)-D-chiro-inositol 1-phosphate (1) and 6-O-(2-amino-2-deoxy-alpha-D-glucopyranosyl)-D-myo-inositol 1-phosphate (2), have been synthesized from selectively protected and enantiomerically pure D-chiro- and myo-inositol derivatives. The D-chiro-inositol unit was prepared in a multigram scale from D-glucose using the Ferrier's carbocyclization route, and it was transformed into the corresponding myo epimer by an oxidation-reduction sequence. The trichloroacetimidate method was applied efficiently for the key glycosylation of the inositol derivatives.
