A simple and efficient protocol has been developed for the synthesis of new1,2,3-triazole-2,3-dihydroquinazolin-4[1H]-one (DHQ) conjugates(6a?j) via ultrasound-assisted, solvent-free ionic liquid [HDBU][HSO4]-catalyzed reaction in good to excellent yields. This non-conventional, ultrasound-assisted route has taken the reactions over the conventional reflux method to provide good to excellent yields of the corresponding products (6a?j) in a very short time. In addition, mild reaction conditions, tolerance to functionalized substrates, ease of product isolation, prevention of its over oxidation and reusability of catalyst [HDBU][HSO4] are some key striking features of the methodology. The newly synthesized derivatives (6a?j) were screened for antioxidant activity using 1,1-diphenyl-2-picryl hydrazyl (DPPH) assay and are found to be a potent scavenger. The compounds 6b, 6c, 6d, 6e and 6i showed significant antioxidant activity. Molecular docking studies showed significant binding affinity in the active site of myeloperoxidase (MPO) enzyme and hence scavenged by inhibition of MPO. In silico ADMET and pharmacokinetic studies of the conjugates are very promising; a cumulative body of evidence suggests their medicinal value as a potential orally active drug candidate.

A general metal-free route to 1,4-disubstituted and 1,4,5-trisubstituted 1,2,3-triazoles was developed. α-Haloacroleins reacted with organic azides in a DMSO/H2O mixture solvent at room temperature to produce 1,4-disubstituted triazoles (up to 99%) with exclusive regioselectivities. This protocol is convenient and scalable with a broad substrate scope including aliphatic and aromatic azides. The resulting triazoles exhibited an aldehyde group at the C4 position and demonstrated synthetic utilizations. One 1,2,3-triazole compound containing diastereotopic protons was also identified.
