RESUMO
A oxidação de 5,6-diamino-1,3-dimetil-2,4-dioxopirimidina (H2ddd) por perrenato (ReO4-) leva à formação de 1,3-dimetilaloxano, que condensa com H2ddd não-oxidado para produzir 1,3,6,8-tetrametilpirimidopteridino-2,4,5,7-tetrona (tppt). A estrutura do tppt consiste de um anel pirazínico central e dois anéis pirimidínicos terminais em posições cis. Os ângulos diedros entre os anéis pirazina e pirimidina são de 1,08° e 1,20°.
