Abstract
New fluorinated 4H-benzo[h]chromen-4-one and 4H-pyrano[3,2-h]quinolin-4-one derivatives are obtained in moderate to good yields, through a one-pot aldolization-intramolecular SNAr process, from the tetrakis(dimethylamino)ethylene (TDAE) mediated reductive cleavage of two N,N-dimethylamino-bis-chlorodifluoroacetyl substrates in the presence of heteroaryl aldehydes.
