3-dialky; quinazoline-2,4-diones 9 has been synthesized on polymeric support by a three step approach. Addition of isocyanates or amines to a polymer-supported anthranilate derivative affords urea 6 which can be cyclized to 3-alkyl quinazolinedione 7. N-Alkylation at the 1-position and cleavage from the resin affords 9a-o in high yield and purity.
