Through a radical solvothermal polymerization method, we synthesized two porous organic polymers based on Tr?ger's base (POP-TB and POP-Me-TB) from the corresponding vinyl-functionalized monomers (2,8-divinyl-6H,12H-5,11-methanodibenzo[b,f]diazocine and 2

A metal-organic framework (MOF), NH2-MIL-101(Al), which acts as a bifunctional, site-isolated Lewis acid-Bronsted base heterogeneous catalyst, catalyzes a tandem Meinwald rearrangement-Knoevenagel condensation reaction with remarkable substrate selectivity.

We report on a one-pot, multistep process in which styrene derivatives are selectively hydroformylated to give branched aldehydes, which in turn, are condensed with reactive methylene compounds (malononitrile, ethyl cyanoacetate), and then hydrogenaled. T
Aliphatic aldehydes in multicomponent syntheses of 4-alkyl-substituted partially hydrogenated quinolines, fused 4H-pyrans, and 2-amino-4-ethyl-5- methylbenzene-1,3-dicarbonitrile

The Knoevenagel condensation of aliphatic aldehydes with CH acids, malonodinitrile, cyanothioacetamide, cyclohexane-1,3-dione, dimedone, 4-hydroxycoumarin, 3-aminophenol, and N-(cyclohex-1-enyl)-morpholine leads to formation of 4-alkyl-substituted partially hydrogenated quinolines, fused 4H-pyrans, and 2-amino-4-ethyl-5-methylbenzene-1,3-dicarbonitrile. The structure of the latter was proved by the X-ray diffraction data. Pleiades Publishing, Inc., 2006.
Synthesis and in vitro antifungal activity of 1-amino-3,4-dialkylnaphthalene-2-carbonitriles and their analogues
Wilamowski, Jarosaw,Kulig, Ewa,Sepio, Janusz J.,Burgie, Zbigniew J.
, p. 625 - 632 (2007/10/03)
Twenty-four 3- and/or 4-alkyl-substituted 1-aminonaphthalene-2-carbonitriles and their analogues were prepared and evaluated for growth-inhibiting activity against four phytopathogenic fungi: Fusarium culmorum, Alternaria brassicicola, Botrytis cinerea an
Silica gel catalysed Knoevenagel condensation in dry media under microwave irradiation
De La Cruz, Pilar,Diez-Barra, Enrique,Loupy, Andre,Langa, Fernando
, p. 1113 - 1116 (2007/10/03)
Neutral silica gel catalysed efficiently the Knoevenagel condensation of carbonyl compounds on malononitrile in dry media under microwave irradiation. Synergy between dry media and microwaves is shown.
Asymmetric Induction in Carbonyl Analogues: Comments on Models
Kruger, Diana,Sopchik, Alan E.,Kingsbury, C.A.
, p. 778 - 788 (2007/10/02)
Organometallic reagent additions to certain carbonyl analogues are reported.The compounds in question have C=C(CN)2 or C=C(CO2R)2 in place of CO.The ground-state conformation of these analogues is quite specific.Some of the additions obey the Cram et al. rules for asymmetric induction but require that approach of the organometallic reagent occurs over the L group in the ground-state conformation.This is taken as an indication that the ground-state conformation is not relevant, in agreement with the Curtin-Hammett principle.In other cases, little asymmetric induction is observed.A third type of behavior concerns opposite modes of addition to the dicyanide vs. the diester substrates.The variability of the data are discussed in terms of the validity of rules for asymmetric induction.Secondary isotope effects are explored in an attempt to resolve the dichotomy between additions to cyclic vs. acyclic ketones.The suggestion is made that the dichotomy in stereochemistry of addition may be related to a kinetically significant conformational change in cyclohexanones vs. acyclic substrates or cyclopentanones.
