Abstract: | N-(Trifluoromethylsulfonyl) and N-arylsulfonyl polychloroacetaldehyde imines reacted with pyrrole, 1-alkyl-, 1-benzyl-, and 1-(4-nitrophenyl)-substituted pyrroles,
and bis-pyrroles to give the corresponding 2-1-(sulfonylamino)polychloroethyl]-1H-pyrroles or mixtures of 2- and 3-1-(sulfonylamino)polychloroethyl]-1H-pyrroles, depending on the nature of the Schiff base and substituent on the pyrrole nitrogen atom and reaction conditions.
The first synthesis of 2,5-disubstituted NH-pyrrole by reaction of pyrrole with Schiff bases was described. |
