摘要
将金鸡纳生物碱衍生物用于催化β-萘酚和芳香酰亚胺的不对称aza—Friedel—Crafts反应制备Betti碱衍生物.考察溶剂、温度及催化剂用量对反应催化性能的影响.结果表明,最佳催化条件为10%催化剂1c,甲苯为溶剂,0℃反应.得到了70%~86%的化学产率和最高达80%ee的对映选择性.
Cinchona alkaloid derivatives as organocatalysts were applied in asymmetric aza-Friedel-Crafis reaction of β-naphthol with aryl aldimines, to synthesize Betti base derivatives. The effect of solvent, temperature and catalyst loading ammount were investigated. The optimized conditions were confirmed to include toluene as the solvent with a 10% loading of catalyst lc at 0 ℃. The products were obtained in 70% - 86% yield with up to 80% ee.
