Diastereoselective synthesis of pyrrolo[1,2-c]imidazoles is reported from three-component reaction of chiral thiohydantoins, aldehydes, and malononitrile in the presence of NEt3. The antioxidant properties of the obtained products were evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay. Among the products, compound 4l possessing NH2 and NH groups and bromine atom at 4-position of the aromatic ring displayed the highest antioxidant activity (90%). Also, their antibacterial activities were explored against gram-positive and gram-negative bacteria using disc diffusion method. Among the synthesized compounds, 4a with chlorine atom at para position of the aromatic ring, and methyl group (the smallest alkyl group) at 7-position, displayed the best antibacterial activity against the tested gram-positive bacteria.

New thiazole derivatives of the general formula I STR1 and their salts with physiologically acceptable acids are described as well as a process for their manufacture. The new compounds exhibit histamine H-2 antagonist activity and may thus be used to inhi
