A series of 5,5-bis(trifluoromethyl)-5,6-dihydropyrimido[4,5-d]pyrimidine-2,4(1H,3H)-diones has been prepared by the cyclocondensation of N-acylimines of hexafluoroacetone and 6-aminouracils. The obtained compounds were screened for their activities against Gram-positive (Staphylococcus aureus, Staphylococcus epidermidis and Bacillus anthracis) and Gram-negative (Escherichia coli) bacteria, as well

observed when 4,4-bis(trifluoromethyl)-5-hydroxyimidazoline 5 was treated with a variety of bases to afford the biologically interesting 4-(trifluoromethyl)imidazole analogs (9 and 10). A unique mechanism was proposed for this transformation, supported by isolating and trapping the hypothesized intermediates. Heating of 5 with Et(4)NCN in DMSO provided 19, which was clearly derived from the proposed
