A new two step procedure for the synthesis of methyl 2,3-anhydro-α-d-lyxofuranoside and methyl 2,3-anhydro-β-d-ribofuranoside from d-xylose involving the intramolecular Mitsunobu reaction is presented. Likewise, methyl 2,3-anhydro-α-l-lyxofuranoside is obtained from l-arabinose. Cyclic sulfites with d-ribo configuration, synthetic equivalents of the corresponding anhydrosugars, are prepared in three steps from d-ribose.
本研究提出了一种新的两步法,通过分子内 Mitsunobu 反应从 d-xylose 合成甲基 2,3-anhydro-δ-d-lyxofuranoside 和甲基 2,3-anhydro-δ-d-ribofuranoside。同样,从 l-arabinose 中也得到了甲基 2,3-anhydro-δ-l-lyxofuranoside。以 d- 核糖为原料,通过三个步骤制备出具有 d-ribo 构型的环状亚硫酸盐,即相应无水糖的合成等价物。
