Di-tert-butyl diethylphosphoramidite as the phosphitylating reagent in the preparation of 3-deoxy-3-C-methylene-d-ribo-hexose-6-phosphate and 3-deoxy-3-C-methylene-d-erythro-pentose-5-phosphate

3-deoxy-3-C-methylene-1,2-O-isopropylidene-alpha-D-ribo-hexofuranose. The preparation of the phosphorylated unsaturated sugars employed di-tert-butyl diethylphosphoramidite as the phosphitylating reagent. The removal of all the protecting groups was done under acidic conditions in the ultimate step. The unsaturated sugar phosphates were competitive inhibitors but neither substrates nor inactivators of
用常见的中间体3-deoxy-3制备3-deoxy-3-C-亚甲基-D-核糖己糖-6-磷酸酯和3-deoxy-3-C-亚甲基-D-赤-戊糖-5-磷酸酯-C-亚甲基-1,2-O-异亚丙基-α-D-核糖-呋喃糖。磷酸化不饱和糖的制备使用二叔丁基二乙基亚磷酰胺作为磷酸化试剂。在最终步骤中,所有保护基的去除均在酸性条件下进行。不饱和糖磷酸酯是竞争性抑制剂,但既不是6-磷酸葡萄糖和5-磷酸核糖异构酶的底物也不是灭活剂。
