Abstract:

Sulfamic acid catalyses the one-pot three components coupling of aldehydes, anilines and electron rich dienophiles such as dihydropyran, dihydrofuran and ethyl vinylether resulting in the formation of pyrano, furano and ethoxy benzopyrans.

Keywords: sulfamic acid, three- component coupling, diastereoselective, pyranobenzopyran, furanobenzopyran
