Click chemistry: Studies on the synthesis of novel fluorous tagged triazol-4-yl substituted quinazoline derivatives and their biological evaluation – Theoretical and experimental validation
摘要:
The formation of N- and O-propargylated quinazoline derivatives 2, 3 from quinazol-4-ones 1 was theoretically predicted by optimizations at B3LYP/6-31G* level, analysed kinetically and thermodynamically. Theoretical predictions are validated by experiment to observe the trends and found deviation. Thus, compound I was propargylated in basic media to obtain compound 2 and 3 in definite proportions. Each compound was further subjected to [3 + 2] cycloaddition using perfluoroalkyl azides through Click reaction under Sharpless conditions, and obtained a series of novel perfluoroalkyl-1H,1,2,3-triazol-4-yl substituted quinazolines 4, 5, and 6. All the compounds were screened for antimicrobial activity and identified potential compounds. (C) 2009 Published by Elsevier Masson SAS.
摘要 N-氟苯磺酰亚胺(NFSI)通过钯催化以中等到良好的产率实现了2-芳基苯并[ d ]恶嗪酮的单氟化。在硝酸盐的促进下,该反应提供了经济和环境友好的策略。单氟2-芳基苯并[ d ]恶嗪酮的合成与许多常见的官能团具有良好的相容性。讨论了这种单氟化的可能机理。 N-氟苯磺酰亚胺(NFSI)通过钯催化以中等到良好的产率实现了2-芳基苯并[ d ]恶嗪酮的单氟化。在硝酸盐的促进下,该反应提供了经济和环境友好的策略。单氟2-芳基苯并[ d ]恶嗪酮的合成与许多常见的官能团具有良好的相容性。讨论了这种单氟化的可能机理。

4H-3,1-Benzoxazin-4-ones of the structural types 3 and 4 are accessible by cyclization reactions. The introduction of the phosphonate group was achieved by way of Wohl-Ziegler bromination and subsequent Michaelis-Arbuzow reaction with a trialkyl phosphite. Pharmacological investigations on isolated left atria, ileum specimens, and Langendorff hearts as well as in vivo circulatory studies on anesthetized
结构类型3和4的4 H -3,1-苯并恶嗪-4-酮可通过环化反应获得。通过Wohl-Ziegler溴化和随后与亚磷酸三烷基酯的Michaelis-Arbuzow反应来实现膦酸酯基团的引入。对离体的左心房,回肠标本和Langendorff心脏的药理研究以及对麻醉大鼠的体内循环研究显示,膦酸酯4具有钙拮抗作用。而2-(芳基乙烯基)苯并恶嗪酮引起明显的负性变力作用,化合物3e 对平滑肌组织表现出松弛作用,并显着增加了通过Langendorff心脏的冠状动脉血流量。

implicated to drug resistance. More and more researches have suggested that CYP1B1 is a new target for cancer prevention and therapy. Various CYP1B1 inhibitors with a rigid polycyclic skeleton have been developed, such as flavonoids, trans-stilbenes, and quinazolines. To obtain a newclass of CYP1B1 inhibitors, we designed and synthesized a series of bentranil analogues, moreover, IC50 determinations
