A model for determination of multicomponent diffusion coefficients in foods
(Elsevier, 2003-12)
The simultaneous diffusion of NaCl, lactic acid and water in cheese during brining, were experimentally and theoretically evaluated using multicomponent and pseudobinary mass transport models. The average concentration ...
A MODEL FOR CALCULATING THE DENSITY OF AQUEOUS MULTICOMPONENT ELECTROLYTE SOLUTIONS
(Sociedad Chilena de Química, 2008)
Niobium Pentachloride Catalyzed Multicomponent Povarov Reaction
(Georg Thieme Verlag Kg, 2012-08-01)
A single-step method for the synthesis of furan-and pyranoquinoline derivatives through multicomponent Povarov reactions between aniline derivatives, benzaldehyde and two different enol ethers (2,3-dihydrofuran and ...
Niobium Pentachloride Catalyzed Multicomponent Povarov Reaction
(Georg Thieme Verlag Kg, 2012-08-01)
A single-step method for the synthesis of furan-and pyranoquinoline derivatives through multicomponent Povarov reactions between aniline derivatives, benzaldehyde and two different enol ethers (2,3-dihydrofuran and ...
NbCl5-Promoted Synthesis of 4-Aryl-3,4-dihydrocoumarins by Multicomponent Reaction
(Georg Thieme Verlag Kg, 2012-11-01)
Substituted 4-aryl-3,4-dihydrocoumarins are synthesized from multicomponent reactions between phenols, dimethyl malonate, and aryl aldehydes catalyzed by niobium pentachloride. This new method is simple, cost-effective, ...
Niobium pentachloride promoted synthesis of tetrahydropiridines by multicomponent reaction
(2013)
One-pot multicomponent synthesis of tetrahydropyridine derivatives between aniline derivatives, benzaldehyde and two different β-keto ester (methyl and ethyl acetoacetate) using niobium pentachloride as catalyst under mild ...
ONE-POT SYNTHESIS OF ISOQUINUCLIDINE DERIVATIVES THROUGH MULTICOMPONENT AZA-DIELS-ALDER REACTIONS PROMOTED BY NIOBIUM PENTAETHOXIDE
(Raman Publ, 2015-01-01)
The bicyclic isoquinuclidine system can be found in many natural products and has several pharmacological properties. In this paper is described an one-pot sysnthesis of Isoquinuclidine derivatives through multicomponent ...
Multicomponent reactions mediated by NbCl5 for the synthesis of phthalonitrile-quinoline dyads: Methodology, scope, mechanistic insights and applications in phthalocyanine synthesis
(2018-04-01)
Herein, we demonstrate the efficiency of NbCl5 to promote a multicomponent reaction (MCR) for the synthesis of a library of phthalonitrile-quinoline dyads, which are very useful and new functionalized building blocks for ...
New method for the synthesis of chromeno[4,3-b]chromene derivatives via multicomponent reaction promoted by niobium pentachloride
(2017-01-01)
Chromeno[4,3-b]chromene derivatives were synthesized from multicomponent reaction between 4-hydroxycoumarin, aryl aldehyde derivatives and 1,3-cyclohexanedione promoted by niobium pentachloride. This new method is simple, ...
Synthesis of 4H-chromenes promoted by NbCl<inf>5</inf> through multicomponent reaction
(2015-06-25)
Abstract Multicomponent reactions between phenols, β-ketoesters, and benzaldehydes for the synthesis of 4H-chromenes derivatives promoted by niobium pentachloride (NbCl<inf>5</inf>) were carried out, providing good yields ...
