Oxyselenenylation of 3,4-dihydro-2H-pyran with (S,S)-hydrobenzoin and subsequent stereoselective transformations afforded the enantiopure L- and D-arabinose while a disaccharide, 6-O-(β-D-arabinopyranosyl)-1,2∶3,4-di-O-isopropylidene-α-D-galactopyranose (13) was synthesized from 3,4-dihydro-2H-pyran by utilizing the same methodology.
利用(S,S)-羟基苯偶姻对3,4-二氢-2H-吡喃进行氧化碲化反应,并经过后续的立体选择性转化,合成了手性纯的L-和D-阿拉伯糖;通过采用相同的方法,从3,4-二氢-2H-吡喃出发,合成了二糖6-O-(β-D-阿拉伯呋喃糖基)-1,2∶3,4-二-O-异亚丙基-α-D-半乳吡喃糖(13)。
