Base-Promoted Synthesis of 2-Aryl Quinazolines from 2-Aminobenzylamines in Water

A 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 reaction mixture for the purification of the solid products circumvents huge solvent-consuming workup and column chromatographic techniques, which make the overall process more sustainable and economical.

Efficient aerobic oxidative synthesis of 2-aryl quinazolines via benzyl C-H bond amination catalyzed by 4-hydroxy-TEMPO

A novel and efficient aerobic protocol for the oxidative synthesis of 2-aryl quinazolines via benzyl C-H bond amination by a one-pot reaction of arylmethanamines with 2-aminobenzoketones and 2-aminobenzaldehydes has been carried out using the 4-hydroxy-TEMPO radical as the catalyst, without any metals or additives.

Novel anti-inflammatory and analgesic heterocyclic amidines that inhibit nitrogen oxide (NO) production

Heterocyclic amidines with anti-inflammatory and analgesic activity that inhibit nitrogen oxide production, of formula (I): in which:G1 and G2 are hydrogen, halogen, hydroxyl, C1-C4 alkoxy, C1-C4 alkyl, and an amidino substituent of formula Q, provided that, for each compound of formula (I), only one of the two substituents G1 or G2 is an amidino substituent of formula Q: and in which the substituents W, Y and X are combined to form 9- or 10-membered bicyclic heteroaromatic derivatives containing up to 2 hetero atoms in the same ring; andZ is an aryl or heteroaryl group, a linear or branched C1-C6 alkyl or alkenyl chain, a C1-C4 alkyl-aryl group or a C1-C4 alkyl-heteroaryl group.
