One-pot Syntheses of Some New 2,4(1H,3H)-quinazolinedione Derivatives in the Absence of Catalyst
Mohammadi, Ali Asghar
, p. 2075 - 2078 (2017)
A facile, rapid and one-pot procedure for the synthesis of some new 2,4(1H,3H)-quinazolinediones is described. The method involves the one-pot condensation of isatoic anhydride, primary amine and carbonyl diimidazole (CDI) in the absence of organic or inorganic catalyst. It affords the corresponding product in high yield.

Regioselective C-H oxidation of aliphatic molecules with synthetic catalysts is challenging. We incorporated substrate-recognition sites into a ruthenium porphyrin-heteroaromatic N-oxide catalytic system in order to characterise its regioselectivity for t

experimental part, p. 341 - 349 (2011/11/12)
A series of quinazolinone derivatives were synthesized by the reaction of 2-aminobenzamides and triethyl orthoformate or triphosgene in ionic liquid of [BMIm]BF4 at 80 °C catalyzed by iodine in good yields. Compared to other methods, this new procedure has the advantages of mild reaction conditions, good yields, operational simplicity, and environmentally friendly procedure.
