High pressure-assisted low-loading asymmetric organocatalytic conjugate addition of nitroalkanes to chalcones
Cholewiak, Agnieszka,Adamczyk, Kamil,Kopyt, Micha?,Kasztelan, Adrian,Kwiatkowski, Piotr
supporting information, p. 4365 - 4371 (2018/06/22)
The application of high pressure (up to 9 kbar) allows for relatively fast (1-5 h) and highly enantioselective 1,4-addition of nitromethane and 2-nitropropane to chalcones at room temperature with substantial reduction of catalyst loading (0.2-1 mol% of cinchona alkaloid-based thioureas and squaramides). Various γ-nitroketones were obtained at 9 kbar with high yield and enantioselectivity (up to 98%), whereas in control experiments at atmospheric pressure usually only a small amount (10%) of products were formed after 20 h.

A novel class of 5-amino-N′-(1-(pyridin-4-yl)ethylidene)-1H-pyrazole-4-carbohydrazides and 8-(pyridin-4-yl)pyrido[2,3-d][1,2,4]triazolo[4,3-a]pyrimidin-5(1H)-ones was synthesized from reaction of 2-cyano-N′-(1-(pyridin-4-yl)ethylidene)-acetohydrazide and
A regioselective and convenient one-pot multicomponent synthesis of 9-amino-3,5-diaryl-4,9-dihydro-5H-[1,2,4]triazolo[5,1-c][1,2,4]triazepine-8-thiol

An efficient and environment-friendly procedure for the synthesis of a new series of nitrogen bridge-head [1,2,4]triazolo[5,1-c][1,2,4]triazepine derivatives through one-pot three-component reaction of polyfunctional triazole with aromatic aldehydes and acetophenone derivatives using alcoholic sodium hydroxide solution. The same new products were prepared in classical route through reaction of triazole with the corresponding chalcones under the same conditions.
EGFR/HER-2 inhibitors: Synthesis, biological evaluation and 3D-QSAR analysis of dihydropyridine-containing thiazolinone derivatives

, p. 21445 - 21454 (2015/03/30)
A series of dihydropyridine containing thiazolinone derivatives (4a-4r) have been designed, synthesized and their biological activities evaluated as potential EGFR and HER-2 kinase inhibitors and in tumor cell antiproliferation. The synthesized compounds
Iron-oxide nanoparticles mediated cyclization of 3-(4-chlorophenyl)-1- hydrazinylisoquinoline to 1-(4,5-dihydropyrazol-1-yl)isoquinolines
Nawaz Khan,Manivel,Prabakaran,Jin, Jong Sung,Jeong, Euh Duck,Kim, Hyun Gyu,Maiyalagan
experimental part, p. 571 - 582 (2012/06/01)
Iron-oxide nanoparticles were obtained using chitosan templates and their crystalline character and particle size have been confirmed through powder x-ray diffraction and transmission electron microscopy measurements. The particle sizes were found to be 10-25 nm. The diversified chalcones 2 were reacted with 1-hydrazinylisoquinoline 1 in the presence of iron-oxide nanoparticles to the corresponding pyrazolines 3a-j in high yield and purity. The pyrazolines were characterized by spectroscopic techniques. Springer Science+Business Media B.V. 2011.
Claisen-schmidt condensation catalyzed by metal-organic frameworks
Dhakshinamoorthy, Amarajothi,Alvaro, Mercedes,Garcia, Hermenegildo
experimental part, p. 711 - 717 (2010/06/13)
Metal-organic framework [Fe(BTC) (BTC = 1,3,5-benzenetricarboxylic acid)] is a convenient heterogeneous catalyst for the carbon-carbon bond forming reaction in toluene between acetophenone and benzaldehyde to give selectively chalcone in high yield. Fe(BTC) appears as a general catalyst able to synthesize selectively different chalcone derivatives bearing various functionalities. Fe(BTC) could be recycled with no significant loss of catalytic efficiency and crystallinity in subsequent runs.
Synthesis of 4-pyrido-6-aryl-2-substituted amino pyrimidines as a new class of antimalarial agents
