The pyrimidine sulfones 10, R = Me; Nu = OMe, NEt2, SPh, H and 11, R = Ph; Nu = OMe were synthesised from the dihydrothienopyrimidones 7, R = Me, Ph by conversion to the chloro derivatives 8 followed by oxidation with mCPBA and reaction with the appropriate nucleophile or hydrogen and Pd. Heating of the sulfones in 1,2,4-trichlorobenzene gave the pyrimidine o-quinodimethanes which were intercepted in Diels-Alder reactions to give tetrahydroquinazolines.
