efficiently synthesized from d-arabinose by using a stereoselective nitromethane addition reaction to form a branched nitropyranose (6) as a key step. Furthermore, two biologically active pseudo-β-d-arabinofuranosylnucleosides, (+)-cyclaradine and (+)-1-pseudo-β-d-arabinofuranosyluracil, were also synthesized from the nitrocyclopentene derivative (12), which was prepared from a synthetic intermediate
光学活性的伪-糖,伪-α-d阿拉伯呋喃糖,被有效地从d阿拉伯糖通过使用立体选择性硝基甲烷加成反应以形成支化nitropyranose(合成6),为关键步骤。此外,还由硝基环戊烯衍生物(12)合成了两个具有生物活性的伪β-d-阿拉伯呋喃糖基核苷,(+)-环花生碱和(+)-1-伪-β-d-阿拉伯呋喃糖基尿嘧啶,其是由合成的硝基环戊烯衍生物制备的假-阿拉伯呋喃糖的中间体,通过迈克尔型反应引入核酸碱基部分。
