Abstract: 
A one-pot, catalyst- and solvent-free approach has been developed for the stereoselective synthesis of fluorinated tetrahydropyrimido [1, 2-b] benzothiazoles. The three-component condensation reaction of an aldehyde and a trifluoromethyl - dicarbonyl compound in the presence of 2-aminobenzothizole occurs in high yields at 90oC.
