Abstract A practical approach was developed for the synthesis of 4-arylquinazoline compounds through a one-pot nucleophilic arylation/alkylation of 2-chloroquinazoline with aryl lithium compounds generated in situ, followed by ring oxidation. The obtained 2-chloro-4-arylquinazoline adducts were further used as versatile intermediates that undergo a variety of synthetic transformations to provide functionalized
摘要 已开发出一种实用的方法,该方法是通过2-氯喹唑啉与原位生成的芳基锂化合物的一锅亲核芳基化/烷基化反应,然后进行环氧化,来合成4-芳基喹唑啉化合物。所获得的2-氯-4-芳基喹唑啉加合物还用作通用中间体,该中间体经过各种合成转化以提供官能化的喹唑啉化合物。芳基化中间体二氢喹唑啉也被精制为三环二氢咪唑并[2,1- b ]喹唑啉酮。 已开发出一种实用的方法,该方法是通过2-氯喹唑啉与原位生成的芳基锂化合物的一锅亲核芳基化/烷基化反应,然后进行环氧化,来合成4-芳基喹唑啉化合物。所获得的2-氯-4-芳基喹唑啉加合物还用作通用中间体,该中间体经过各种合成转化以提供官能化的喹唑啉化合物。芳基化中间体二氢喹唑啉也被精制为三环二氢咪唑并[2,1- b ]喹唑啉酮。
