number of centers of asymmetry were formed with nearly complete diastereoselectivity. Considerable differences were observed in the ring-closing abilities of the unsubstituted and phenyl-substituted aminonaphthols 1 and 2 and of the regioisomeric compounds 1 and 3.
通过1-(α-氨基苄基)-2-萘酚(贝蒂碱:1),1-氨基甲基-2-萘酚(2)和2-(α-氨基苄基)-1-的简单或多米诺环封闭反应萘酚(反向Betti碱:3)与光气,苯甲磺酸乙酯,2-羧基苯甲醛,乙酰丙酸,水杨醛/福尔马林或水杨醛/乙醛,萘[1,2- e ] [1,3]恶嗪和萘[2,1-制备了e ] [1,3]恶嗪衍生物。1和3的所有氮桥多环衍生物包含许多不对称中心的化合物几乎具有完全非对映选择性。在未取代的和苯基取代的氨基萘1和2以及区域异构化合物1和3的闭环能力上观察到相当大的差异。
