摘要

结果表明，负载在4Å分子筛上的镧是一种高效的非均相催化剂，可由均邻苯二酸酐、芳香族醛和胺类组分乙酸铵或芳烷基胺一锅合成1,2,3,4-四氢异喹啉-4-羧酸衍生物，收率高至优异。该催化剂可以很容易地回收和重复使用，而不会显著损失其初始活性。

Heterogeneous Catalytic Method for the One-pot Three-component Synthesis of Isoquinolonic Acid Derivatives Catalyzed by a 4Å Molecular Sieves Supported Lanthanum Catalyst

Lanthanum supported on 4Å molecular sieves proved to be an efficient heterogeneous catalyst for the one-pot three-component synthesis of 1,2,3,4-tetrahydroisoquinolinone-4-carboxylic acid derivatives from homophthalic anhydride, aromatic aldehydes and an amine component, ammonium acetate or aralkyl amines, with good to excellent yields. The catalyst could be recovered easily and reused without significant loss of its initial activity.
