atom-efficient synthesis of 2-substituted quinazolines is developed by a CsOH-mediated direct aerobic oxidative reaction of the readily available and stable 2-aminoarylmethanols and nitriles. Effectively working as the promoter in the alcohol oxidation, nitrile hydration, and cyclocondensation steps, CsOH is the best base for the reaction. A similar method can also be extended to the synthesis of substituted

be the key reagent in absence or presence of catalytic amount of molecular iodine (I2)/zinc chloride (ZnCl2) to construct quinazoline scaffold from 2-aminobenzylamine and a variety of easily available aldehydes, aryl and aliphatic amines, aliphatic and aryl alcohols and nitriles. This protocol provides mild and robust conditions along with great versatility to synthesize 2-substituted quinazolines from
Iron-catalyzed aerobic oxidativefunctionalization of sp3 C–Hbonds has been developed for the construction of N-heterocycles from easily available carboxylic acid derivatives and o-substituted anilines. This transformation represents a widely applicable protocol to N-heterocycles using biofriendly iron as a catalyst in combination with molecular oxygen or air as the sole oxidant.

The present invention introduces compounds that are adenosine-kinase inhibitors. We provide a process of protecting tissues and organs like heart, brain and kidneys affected by ischemia, and of treating heart insufficiency, myocardium infarct, arrhythmia, arterial hypertension, atherosclerosis, coronary artery re-stenosis after angioplasty, chronic renal insufficiency, cerebral vascular accident, and chronic inflammatory diseases (e.g. rheumatoid arthritis). We also provide the adenosine-kinase inhibitor effect of compounds derived from quinazolines, which were previously known as reversible inhibitors of tyrosine-kinases from the family of epidermic growth factor receptors (EGFR).
