摘要: 设计并合成了2个新的手性源S-(一)-α-取代-2-羟基-5-甲基苄胺,从该手性源合成了4个光活性铜络合物,考察了它们对苯乙烯、1,1-二苯乙烯和2,4-二甲基-2,5-已二烯的不对称环丙烷化反应的光学诱导活性.结果表明,由S-(一)-1-(2-羟基-5-甲基苯基)-2-甲基丙胺与2-羟基萘甲醛缩合而得到的Schiff碱为配体的铜络合物的诱导活性最佳.

Abstract: Four chiral copper(Ⅱ) complexes derived from two novel chiral compounds (S)-(-)-α-substituted-2-hydroxy-5-methylbenzylamine were synthesized. All the complexes were used as catalysts in the asymmetric cyclopropanation reaction of styrene, 1,1-diphenylethylene and 2,5-dimethyl-2,4-hexadiene. It is found that the more effective catalysts are related to complexes with ligands prepared from optically active amine and 2-hydroxy-1-naphthylaldehyde.

Key words: Optically active amine, Olefins, Copper complex, Asymmetric cyclopropanation
