An efficient and a novel approach for the synthesis of furochromene and furopyran scaffolds are described. Benzyl halides undergo oxidation in Kornblum conditions to give the corresponding aldehydes, which in turn undergo 4Â +Â 1 cycloaddition reac

Pyridine N-oxide and silver oxide have been demonstrated to be efficient and mild reagents for the one pot synthesis of pyran analogues from a variety of benzyl halides. Benzyl halides are oxidized in situ to aldehydes, which in turn undergo a three-
