Abstract

A simple one-pot and efficient method is described for the synthesis of 2-hydroxy-3-phenyl-4H-pyrimido[2,1-b][1,3]benzothiazol-4-one and thioxodihydro-4,6(1H,5H)-pyrimidinone derivatives via the reaction of (chlorocarbonyl)phenylketene with 1,3-dinucleophiles such as 2-aminobenzothiazoles and N-arylthioureas respectively. This method offers a simple and convenient route to prepare the title compounds in good to excellent yields in a short reaction time.
