2-(p-Tolyl)-2H-benzotriazole und 2-Phenyl-5-methyl-2H-benzotriazole können mit Anilen aromatischer Aldehyde in Dimethylformamid in Gegenwart von Kaliumhydroxid in 2-(Stilben-4-yl)-2H-benzotriazole bzw. 2-Phenyl-5-styryl-2H-benzotriazole über geführt werden («Anil-Synthese»).

Highly enantio- and diastereoselective three-component inverse electron-demand aza-Diels-Alder reaction of aldehydes, anilines, and isoeugenol derivatives catalyzed by a chiral phosphoric acid catalyst are reported. A wide variety of 2,3,4-trisubstituted tetrahydroquinolines containing an aryl group at the 4-position were obtained in a one-pot process with good to high yields and excellent stereoselectivities (>95:5 dr and up to >99% ee).

A series of Schiff bases (compounds 1–10) were synthesized by condensing heterocyclic/aromatic aldehydes with heterocyclic/aromatic amines through both, conventional method and microwave-assisted synthesis. The compounds were confirmed by means of IR spectroscopy, Mass spectrometry, 1H NMR and elemental analyses. The compounds were assayed for antibacterial activity against selected strains of Gram
