The 2-((E)-3-(2-nitrophenyl)-1-(4-methoxyphenyl) allylidene)malononitrile and 2-((E)-3-(2-chlorophenyl)-1-(4-bromophenyl)allylidene)malononitrile were synthesized and characterized by IR, 1H NMR, and elemental analysis. The molecular structures were further confirmed by X-ray diffraction analysis. The former 1, C19H13N3O3, is triclinic, space group P-1, a = 7.3834(13), b = 10.901(3), c = 11.227(2) Å, α = 88.64(2), β = 71.596(14), γ = 78.186 (18), Z = 2, V = 838.5(3) Å3. The unclassical hydrogen bond of C-H⋯N links the molecules forming polymers. The latter 2, C36H 20Br2Cl2N4, is orthorhombic, space group Pnma, a = 20.900 (4), b = 7.0710 (11), c = 10.9170 (18) Å, Z = 2, V = 1613.4(5) Å3. The same hydrogen bond of C-H⋯N and another type of C-H⋯Cl hydrogen bond link the adjacent molecules forming polymers along a axis. © Springer Science+Business Media, LLC 2010.

The crystal structure of 9-(4-methoxyphenyl)-3,3-dimethyl-10-(4- methylphenyl)-1,2,3,4,5,6,7,8,9,10- decahydroacridin-1,8-dione is determined by X-ray diffraction at 153(2) K. The title compound 1, C22H21N5O6, is triclinic, space group P-1, a = 9.6382(15) Å, b = 11.5847(15) Å, c = 12.4722(11) Å, α = 66.075(9)°, β = 70.176(9)°, γ = 85.800(13)°, Z = 2, V = 1194.1(3) Å3. It is interesting that the central pyridine ring of the acridine moiety is slightly distorted and adopts a boat conformation. The outer sixmembered ring with two methyl groups adopts half-chair conformation, while another outer partially saturated sixmembered ring adopts distorted boat form. In addition, the un-classical hydrogen bonds of C-H...O link the molecules forming polymers in the crystals. © Springer Science+Business Media, LLC 2010.

By controlling the amount of catalyst 1-methyl-3-(2-(sulfooxy)ethyl)-1H-imidazol-3-ium chloride, two new intermediates of Tröger's bases (11, 1,6-dimethyl-3-(4-methylphenyl)-1,4-dihydroquinazolin-3-ium tetrafluoroborate and 12, 8-methyl-2,5-bis-(4-methylphenyl)-3,5,6,7-tetrahydropyrimido[5,6,1-ij]quinazoline-2-ium tetrafluoroborate) were simply obtained from the one-pot reaction of aromatic amine and formaldehyde in ionic liquid at ambient temperature. These results support the mechanism for Tröger's base formation supposed by Fernando Coelho and co-workers. However, the crystal structure of 12 and correlative quantum chemistry calculation results are not reconciled with their report. © 2010 Elsevier Ltd. All rights reserved.

A highly atom-economic one-pot synthesis of five-substituted tetrahydropyridines via a five-component condensation of two equivalents of aromatic aldehyde, two equivalents of aromatic aniline, and one equivalent of β-keto ester catalyzed by silica sulfuric acid is reported. In this reaction, up to five new bonds and one new ring were formed in one pot with water as the only one by-product. © 2013 HeteroCorporation.

Glucose sulfonic acid (GSA) was synthesized for the first time and used as an efficient catalyst for the preparation of tetrahydrobenzo[α]xanthens and tetrahydrobenzo[α]acridines via the reaction of aromatic aldehydes, 2-naphthol (or β-naphthylamine), and dimedone in water. Up to four new bonds and one new ring were formed in one-pot with water as the only by-product in these two reactions. The work opens up a new and efficient synthesis and application of sugar-containing Brønsted acid.© 2013 Elsevier Ltd. All rights reserved.
