with 86% e.e. By lithium aluminum hydride reduction, (+)-4 and (−)-5 were converted to (+)-bicyclo[3.3.1]nonane-2,6-diol (3) and (−)-3 with high optical purity, respectively, and (+)-7 was obtained from (+)-9. Using these optically active diols 3 and 7 as a chiral subunit, optically active crown ethers and podands were prepared and their enantiomer recognition behavior was evaluated by the enantiomer
使用来自圆柱假丝酵母的脂肪酶水解 2,6-二乙酰氧基双环 [3.3.1] 壬烷 (5) 得到 (+)-(1S,2R,5S,6R)-6-乙酰氧基双环 [3.3.1]nonan-2-ol ( 4) 具有 81% ee 和 (-)-(1R,2S,5R,6S)-5 具有 95% ee,以及猪肝酯酶催化的 2,6-二乙酰氧基-3,3,7,7-四甲基双环水解[3.3.1]壬烷 (9) 得到 (-)-(1S,2R,5S,6R)-3,3,7,7-四甲基双环 [3.3.1] 壬烷-2,6-二醇 (7),其中 96 %ee和(+)-(1R,2S,5R,6S)-9与86%ee 通过氢化铝锂还原,(+)-4和(-)-5转化为(+)-双环[3.3。 1]壬烷-2,6-二醇 (3) 和 (-)-3 分别具有高光学纯度,(+)-7 由 (+)-9 获得。使用这些光学活性二醇 3 和 7 作为手性亚基,
