An organocatalyzed protocol has been described for the comprehensive synthesis of 2‐substituted quinazolines usingnitriles as C–N source. The developed reaction conditions are suitable for a wide range of substrates providing the desired products in excellent yields.
catalyst-free direct aerobic oxidative annulation reaction of 2-aminobenzylic amines and α-hydroxy ketones efficiently afforded versatile 5H-1,4-benzodiazepine derivatives by employing air as economic and green oxidant under mild conditions. Interestingly, solvent was found to be crucial to the reaction, so that by using acetic acid as the best solvent an efficient and practical method could be achieved, requiring
2- aminobenzylic胺和α的不含催化剂的直接氧化好氧环反应-羟基酮有效地得到多功能5 ħ通过采用空气作为在温和条件下经济和绿色氧化剂-1,4-苯并二氮杂衍生物。有趣的是,发现溶剂对反应至关重要,因此通过使用乙酸作为最佳溶剂,可以实现一种高效实用的方法,完全不需要催化剂或添加剂。此方法容许广泛2-aminobenzylic胺和α的-羟基酮,并且可以放大到多克合成,并在药学上有活性的一步法合成直接施加N-去甲基美西泮衍生物,揭示了这种新方法在合成 5 H -1,4-苯二氮卓类药物和化学品中的潜力。

transition-metal-free procedure for the synthesis of a highly valuable class of heteroaromatics, quinazolines, was developed by using easily available 2-aminobenzylamines and α,α,α-trihalotoluenes. The transformation proceeded smoothly in the presence of only sodium hydroxide and molecular oxygen in water at 100 °C, furnishing a variety of 2-aryl quinazolines. The crystallization process of the crude

A series of new chemical agents that demonstrate anti-tumor activity are described. The new chemical agents combine two major mechanisms of anti-tumor action. In an embodiment, the agents are capable of both inhibiting EGFR and damaging DNA while also, upon degradation, degrading to an inhibitor of EGFR and to an agent capable of damaging DNA. Moreover, a novel series of molecules capable of releasing two moles of EGFR inhibitor and a potent bi-functional alkylating agent are also described.
