Traceless synthesis of quinazoline-2,4-diones by curtius rearrangement reaction using poly(ethylene glycol) as soluble polymeric support

(Chemical Equation Presented) We have developed an efficient method to synthesize various quinazoline-2,4-diones using polyethylene glycol) as soluble polymeric support. The procedure of this reaction included: formation of acyl azide, efficient Curtius rearrangement, nucleophlic addition with amines to produce ureas, cyclization and concurrent cleavage of the resulted six-membered heterocycle from PEG-support in excellent yields. This method is mild and manipulation is easy.
