A convenient synthesis of furo[3,2-c]pyran-3-carboxylates from 3-bromo-3-nitroacrylates
Novel 4-oxo-4H-furo[3,2-c]pyran-3-carboxylates and 4-oxo- 4H-furo[3,2-c]chromene-3-carboxylates were prepared from available alkyl 3-bromo-3-nitroacrylates and 4-hydroxy-6- methyl-2H-pyran-2-one or 4-hydroxycoumarin, respectively. Their structures were confirmed by NMR and X-ray data.
