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
