Abstract
A one-pot procedure has been developed for the synthesis of α-indolyl-β-nitroacrylates by reaction of β-bromo-β-nitroacrilates with indole and substituted indoles. All indolylnitroacrilates thus obtained have Z configuration of the double bond. According to the X-ray diffraction data, ethyl 2-(1-methyl-1H-indol-3-yl)-3-nitroacrylate is characterized by s-trans conformation of the double C=C bond and indole ring; its crystal packing involves intermolecular hydrogen bonds C-H…O and C-H…π with formation of centrosymmetric dimers which give rise to bilayer supramolecular structures.
