Abstract |
However, in our study, the reactivity of both 4-formyl-1-methyl-2-vinylpyrrole (1) and 2-formyl-1-methyl-4-vinylpyrrole (2) was studied to explore the reactivity of these compounds in view of factors like inductive and mesomeric effects. IR spectra were obtained for nujol mulls using a Perkin-Elmer 577 spectrometer, between 4000 and 625 cm"." H-NMR spectra were measured for ca. 0.3 M solution in CDCl, at 60 MHz using a JEOL JMN FX-100 spectrometer. All chemical shifts are reported relative to tetramethyl silane (ồ= 0) and the deuterated solvent was used as a lock signal for" H-NMR spectra. General Reaction of the vinylpyrrole with DMAD: 3-Formyl-5-vinyl-1-methylpyrrole (0.37 g, 0.003 mol) and hydroquinone (3 mg) in dry chloroform (15 mL) was added to dimethylacetylene-dicarboxylate (042 g), 0.003 mol) in chloroform (10 mL). The mixture was heated at 60 C under nitrogeni for 3 days. The solvent was then … |
