Abstract

On treatment with NaN3/c. H2SO4-HOAc or NaN3/TFA,E-3-benzylidenechromanones are mostly converted toE-β-aminobenzylidenechromanones whileE-3-benzylidenethiochromanones are converted to 3-benzoylthiochromones. A structurally new type of product has been isolated for the reaction ofE-3-benzylidene-4′-methoxychromanone with NaN3/TFA. Mechanistic paths have been suggested for formation of the products.
