A new and simple method for the preparation of 1-aminonaphthalene-2-carbonitrile derivatives has been developed. When 2-(1-arylethenyl)benzonitriles are treated with 2-lithioacetonitrile, 1-amino-4-aryl-3,4-dihydronaphthalene-2-carbonitriles are obtained in good yields. The reaction of 2-(1-aryl-2-methoxyethenyl)benzonitriles with 2-lithioacetonitrile leads to the formation of 1-amino-4-arylnaphthalene-2-carbonitriles in fair-to-good yields.
我们开发了一种制备 1-氨基萘-2-甲腈衍生物的简便新方法。当 2-(1-芳基乙烯基)苯腈与 2-二硫代乙腈反应时,可获得 1-氨基-4-芳基-3,4-二氢萘-2-甲腈,且收率良好。2-(1-芳基-2-甲氧基乙烯基)苯腈与 2-二硫代乙腈反应可生成 1-氨基-4-芳基萘-2-甲腈,收率尚可。
