This review focuses on the recent applications of Burgess reagent in the synthesis of organic compounds, with the emphasis, on the total synthesis of natural occurring products.

An efficient method for the synthesis of 1,2,4,5-tetra substituted imidazoles usingK7Na3P2W18Cu4O68as catalyst is reported. This four-component condensation of benzil, aldehydes, amines, and ammonium acetate proceeds under solvent-free conditions. The catalyst is handling and recoverable.

An effective, novel and rapid one-pot three-component route to quinazolin-4(3H)-ones from commercially available starting materials is described. Isatoic anhydride reacts with acyl chlorides and different amines using a combination of trifluoromethanesulfonic anhydride (Tf 2 O) and 2-chloropyridine (2-ClPy) to produce the corresponding quinazolinone derivatives in good to excellent yields.
