method that canefficiently provide quinazoline-2,4-dione derivatives. Wereport herein a convenient one-pot synthesis of quinazoline-2,4-dione derivatives. We also report on the synthesis of thenaturally occurring alkaloids 2 and 3. Results and DiscussionA two-step reaction for the synthesis of quinazoline-2,4-dione derivatives starting from isatoic anhydride and amineshas already been described.
