1,2-anhydroglucitol-6P, a known inhibitor of glucose-6P isomerase, behaved as a fructose-6P site-directed irreversible inhibitor of bacterial glucosamine-6P synthase. The lack of reproducibility of the aldolase-mediated condensation of dihydroxyacetone phosphate and glycidaldehyde followed by borohydride reduction previously described prompted us to develop a chemical route to this compound and its radiolabelled counterpart. The compound was synthesized in 13 steps from D-arabinose with a 6% overall yield. Tritium introduction was performed at step 11 (3 → 4) allowing isolation of the title compound of high specific radioactivity.
1,2-脱水葡萄糖醇-6P 是一种已知的葡萄糖-6P 异构酶抑制剂,是细菌葡萄糖胺-6P 合酶的果糖-6P 定点不可逆抑制剂。先前描述的醛缩酶介导的磷酸二羟丙酮和缩水甘油醛的缩合以及随后的硼氢化物还原缺乏再现性,这促使我们开发了一种制备该化合物及其放射性标记对应物的化学途径。该化合物由 D-阿拉伯糖经过 13 个步骤合成,总产率为 6%。在步骤11(3→4)中引入氚,从而分离出具有高比放射性的标题化合物。
