treatment with substituted hydrazines, were condensed with acetylene diesters to afford, after a two-fold conjugate addition, a variety of new substituted 1,2,3,4-tetrahydro-4-oxo-2-quinazolineacetic acid esters.
摘要 取代的邻氨基苯甲酰肼是通过用取代的肼处理打开靛红酸酐制备的,与乙炔二酯缩合,经过两倍共轭加成后,得到各种新的取代的 1,2,3,4-四氢-4-氧- 2-喹唑啉乙酸酯。
