A traceless synthesis of 1,2,4-triazolidine-3,5-diones has been achieved through cyclo-elimination from solid-phase. This traceless cyclo-elimination release step is induced by catalytic amount of base or by simply refluxing the urea carbamate intermediate.

An efficient solid phase synthesis of chiral quinazolinediones is described. Immobilized amino acid based urea derivatives 3 undergo a racemization-free heterocyclization upon gentle heating in presence of tetramethylguanidinc to afford fused pyrimidine-2,4-diones 6, which are smoothly NJ-alkylated
