Abstract Starting from d -glucose, a novel sequence of the syntheses leading to (3 S ,5 S ,6 S )-6-ethyl-3,5-dimethyltetrahydro-2 H -pyran-2-one ( 4 ) is described. Key steps are the hydrogenation of 3,5,6-trideoxy-1,2- O -isopropylidene-3- C -methyl-α- d - glycero -hex-3,5-dienose leading to 3,5,6-trideoxy-1,2- O -isopropylidene-3- C - methyl-β- l - lyxo -hexofuranose, and the base-catalyzed cyclisation
摘要从d-葡萄糖开始,描述了导致(3 S,5 S,6 S)-6-乙基-3,5-二甲基四氢-2 H-吡喃-2-酮(4)的合成的新序列。关键步骤是将3,5,6-三苯氧基-1,2-O-异亚丙基-3-C-甲基-α-d-甘油-hex-3,5-二烯糖加氢生成3,5,6-三苯氧基-1,2- O-异亚丙基-3- C-甲基-β-l-lyxo-六呋喃糖,以及碱催化的甲基(2 RS,4 S,5 S)-5-羟基-2环化和异构化将4-二甲基庚酸酯转化为4。可以通过已知方法将化合物4转化为Serrcornin。
