(−)-Shikimate 3-phosphate and (−)-quinate 3-phosphate can be synthesized by selective protection of their trans diol functionality using 2,2,3,3-tetramethoxybutane (TMB) using d-(−)-shikimic acid and d-(−)-quinic acid as starting materials. This versatile reagent facilitates the synthesis of these important biological targets in fewer steps than previously reported. By the proper choice of protecting
(-)-Shikimate 3-phosphate和(-)-quinate 3-phosphate可通过使用d-(-)-shikimic acid使用2,2,3,3-四甲氧基丁烷(TMB)选择性保护其反式二醇官能团来合成以d-(-)-奎宁酸为原料。与以前报道的相比,这种多功能的试剂以更少的步骤促进了这些重要生物靶标的合成。通过保护基团为C-3羟基在d的适当的选择- ( - ) - ( - ) -莽草酸-3-磷酸奎尼酸,它可以在合成转化为关键中间体。
