In this work, a simple and convenient synthesis of a new series of benzo[h]quinoline-based α-arylidene cycloketone derivatives, namely 9-arylidene-9,11-dihydro-8H-benzo[h]pyrano[3,4-b]quinolin-8-ones, has been achieved for the first time in good yields through Claisen–Schmidt condensation reaction of readily synthesized benzo[h]pyrano[3,4-b]quinolin-8-one with aromatic aldehydes under eco-friendly
在这项工作中,简单方便地合成了一系列新的基于苯并[ h ]喹啉的α-亚芳基环酮衍生物,即9-亚芳基-9,11-二氢-8H-苯并[ h ]吡喃并[3,4-]。b ] quinolin-8-ones首次以高收率通过易合成的苯并[ h ]吡喃并[3,4- b ] quinolin-8- a与芳族醛在生态环境下的Claisen-Schmidt缩合反应获得。友好的无溶剂条件。我们的合成策略具有实验简单,试剂便宜和产率令人满意的特点,这将有助于该方法的实用性。
