A series of 2-substituted-4(3H)-quinazolinones 13-20 has been synthesized in good yields using the reaction of double lithiated 2-methylquinazolinone-4 with a variety of aromatic aldehydes. They have been easily transformed in high yields into the corresponding 2-substituted conjugated derivatives 21-28 bearing terminal aryl groups by F3CCOOH mediated dehydration.
使用双锂化的2-甲基喹唑啉酮-4与多种芳族醛的反应,已经以高收率合成了一系列2-取代-4(3 H)-喹唑啉酮13-20。通过F 3 CCOOH介导的脱水,它们很容易以高收率转化成带有末端芳基的相应的2-取代的共轭衍生物21-28。
