A number of mesoionic thiazolo[3,2-a ]pyrimidine-5,7-diones, isoconjugate mesoionic analogs of xanthinc, were prepared by the condensation of 2-alkylaminothiazoles with bis(2,4,6-trichloro-phenyl)malonate esters. The ground state molecular properties and reactions of these compounds were found to be consistent with predictions based upon previous SCF molecular orbital treatments of the π-systems of
