An efficient approach for the construction of 1,3-disubstituted-1,3-dihydroisobenzofuran compounds was developed through tin powder mediated tandem allylation/oxa-Michael addition reaction of o-formyl chalcones with various allyl bromides under mild reaction conditions. This method is easy to operate and can tolerate various functional groups to give the corresponding 1,3-disubstituted-1,3-dihydroisobenzofuran compounds in good to excellent yields.

Key words: tin powder, allyl bromide, o-formyl chalcone, 1,3-dihydroisobenzofuran
