Abstract:

The reactions of 3-nitro-2-trifluoromethyl- and 3-nitro-2-trichloromethyl-2H-chromenes with thiols and aromatic amines proceed via the nucleophilic addition type to the activated double bond to form 2,3,4-trisubstituted chromanes in high yields. The stereoisomeric compositions and structures of the diastereomers were determined by H-1, F-19 NMR and 2D NOESY spectroscopies and X-ray diffraction analysis.
