Abstract
The condensation of 3-(furan-2-yl)- and 3-(thiophen-2-yl)prop-2-enals with nitro-substituted CH acids, namely ethyl nitroacetate, nitroacetone, nitroacetophenone, and nitroacetonitrile, afforded a series of geminally activated nitro dienes, 4-(furan-2-yl)- and 4-(thiophen-2-yl)-1-nitrobuta-1,3-dienes. The product structure was confirmed by NMR and IR spectroscopy.
