(Chemical Equation Presented) N-t-Butylamidines 1 on heating with diphenyl carbonate (2) at 150-180° gave the 1,3,5-triazine-2,4(1H,3H)-dione derivatives 5. Acylation of amidines 1 and cyclocondensation of the resulting carbamates 3 gave [1,3,5,7]tetrazocine-2,6-dione derivatives 4, and subsequent retro-ene reaction and ring contraction afforded triazine derivatives 5.
