A number of 6,9-disubstituted cyclohepta[b]pyrimido[5,4-d]pyrrole-8(6H),10(9H)-dione derivatives have been synthesized in good to moderate yields by the reaction of 6-amino-3-methyluracil derivatives with 2-chlorotropone in an enamine-alkylation process, subsequent condensation of the amino group with the carbonyl function, dehydrochlorination, and dehydration.
