A novel approach to prepare 4-anilinoquinazoline derivatives based on the transformation of indoline-2,3-dione to formamidine was developed. The processes with this approach are simple, efficient, and environmentally friendly. The efficiency of this approach was evaluated by synthesizing 17 4-anilinoquinazolines and comparing the obtained yields with those achievable through conventional synthetic

본 발명은 신규한 화합물 또는 이의 약학적으로 허용가능한 염, 및 이를 유효성분으로 함유하는 인플루엔자 바이러스 감염으로 인한 질환의 예방 또는 치료용 약학적 조성물에 관한 것이다. 본 발명에 따른 화학식 1로 표시되는 신규한 화합물은 인플루엔자 바이러스에 대한 항바이러스 활성이 현저히 우수할 뿐만 아니라, 인간 세포에 대한 세포독성이 없어 인체에 부작용이 적으므로, 이를 유효성분으로 함유하는 약학적 조성물은 인플루엔자 바이러스 감염에 의해 발병되는 독감, 감기, 인후염, 기관지염, 폐렴, 조류독감, 돼지독감, 염소독감 등의 예방 또는 치료용 유용하게 사용될 수 있다.
namide derivatives, N-(5-methyl-1,2-oxazol-3-yl)-4-[(quinazolin-4-yl)amino]benzene-1-sulfonamide (4a) and N-(3,4-dimethyl-1,2-oxazol-5-yl)-4-[(quinazolin-4-yl)amino]benzene-1-sulfonamide (4b), were synthesized and the structures were confirmed by different spectroscopic techniques like FT-IR, 1H NMR, 13C NMR, HRMS and elemental analysis. The crystalstructures were solved by single crystal X-ray diffraction
Microwave-accelerated Dimroth rearrangement for the synthesis of 4-anilino-6-nitroquinazolines. Application to an efficient synthesis of a microtubule destabilizing agent
A useful and rapid access to 4-anilino-6-nitroquinazolines was investigated in a multi-gram scale via microwave-accelerated condensation and Dimroth rearrangement of the starting anilines with imines obtained by reaction of anthranilonitriles with formamide dimethylacetal. A novel short and efficient route to AZiXa (TM) (EPi28495, MPC-6827), a microtubule destabilizing agent and apoptosis inducer, was performed with success demonstrating that well controlled parameters offer comfortable using of microwave technology with safe and environmental benefits.
