Compound: 2,6-Dimethyl-3,5-heptanedione, is researched, Molecular C9H16O2, CAS is 18362-64-6, about Metal- and Oxidant-Free Synthesis of Quinazolinones from β-Ketoesters with o-Aminobenzamides via Phosphorous Acid-Catalyzed Cyclocondensation and Selective C-C Bond Cleavage. Author is Li, Zhongwen; Dong, Jianyu; Chen, Xiuling; Li, Qiang; Zhou, Yongbo; Yin, Shuang-Feng.
A general and efficient phosphorous acid-catalyzed cyclocondensation of β-ketoesters with o-aminobenzamides via selective C-C bond cleavage leading to quinazolinones is developed. This reaction proceeds smoothly under metal- and oxidant-free conditions, giving both 2-alkyl- and 2-aryl-substituted quinazolinones in excellent yields. This strategy can also be applied to the synthesis of other N-heterocycles, such as benzimidazoles and benzothiazoles.
