A Combination of Visible-Light Organophotoredox Catalysis and Asymmetric Organocatalysis for the Enantioselective Mannich Reaction of Dihydroquinoxalinones with Ketones

Rostoll-Berenguer, J.; Blay, G.; Muñoz Roca, María Del Carmen; Pedro, J.R.; Vila, C. (American Chemical Society, 2019-08-02)

[EN] An enantioselective photooxidative Mannich reaction of dihydroquinoxalinones with ketones by the merger of organophotoredox and asymmetric organocatalysis is described. This protocol features very mild reaction ...
Aerobic oxidation of sulfides to sulfoxides catalyzed by gold/manganese oxides

Taketoshi, Ayako; Concepción Heydorn, Patricia; García Gómez, Hermenegildo; Corma Canós, Avelino; Haruta, Masatake (Chemical Society of Japan, 2013-12-15)

Although selective oxidation of sulfides to sulfoxides with molecular oxygen is a difficult reaction due to the overoxidation to sulfone, manganese oxides were found to catalyze the aerobic oxidation of sulfides to sulfoxides ...
Coupling two multistep catalytic cycles for the one-pot synthesis of propargylamines from alcohols and primary amines on nanoparticulated gold catalyst

Corma Canós, Avelino; Navas Escrig, Javier; Sabater Picot, Mª José (Wiley-VCH Verlag, 2012)

[EN] A one-pot reaction was performed with a nanoparticulated gold catalyst. A secondary amine is formed through N-monoalkylation of a primary amine with an alcohol by a borrowing hydrogen methodology in a three-step ...
Enantioselective Friedel-Crafts Alkylation of Indoles with (E)-1-Aryl-4-benzyloxybut-2-en-1-ones Catalyzed by an (R)-3,3-Br2BINOLate-Hafnium(IV) Complex

Muñoz Roca, María del Carmen (Wiley-VCH Verlag, 2013-02-11)

A highly enantioselective Friedel–Crafts reaction of unprotected indoles with (E)-1-aryl-4-benzyloxybut-2-en-1-ones catalyzed by a new chiral [Hf{(R)-3,3′-Br2-BINOL}(OtBu)2]2 complex has been developed to functionalize the ...
iCAREPLAST Datasets

Alabort Martínez, Carles; Sanchis Saez, Javier; Catalán Martínez, David; Serra Alfaro, José Manuel (Universitat Politècnica de València, 2022-06-09)

The aim of iCAREPLAST project is to provide a cost and energy-efficient alternative to recycle and valorise non-recycled plastic waste (ca. 70% of European plastic waste) that, due to their characteristics or their ...
Organocatalytic enantioselective functionalization of indoles in the carbocyclic ring with cyclic imines

Vila, C.; Tortosa, A.; Blay, G.; Muñoz Roca, María Del Carmen; Pedro, J.R. (The Royal Society of Chemistry, 2019-01-07)

[EN] An organocatalytic enantioselective functionalization in the carbocyclic ring of indoles with benzoxathiazine 2,2-dioxides is described using a quinine-derived bifunctional organocatalyst. This aza-Friedel-Crafts ...
Synthesis of Functionalized Indoles with a Trifluoromethy-Substituted Stereogenic Tertiary Carbon Atom Through an Enantioselective Friedel-Crafts Alkylation with beta-Trifluoromethyl-alpha, beta-enones

Blay, G.; Fernández, I.; Muñoz Roca, María Del Carmen; Pedro, J. R.; Vila, C. (John Wiley & Sons, 2010-07-30)

[EN] Chiral complexes of BINOL-based ligands with zirconium tert-butoxide catalyze the Friedel-Crafts alkylation reaction of indoles with beta-trifluoromethyl-alpha,beta-unsaturated ketones to give functionalized indoles ...
Zeolites as catalysts in oil refining

Primo Arnau, Ana María; García Gómez, Hermenegildo (Royal Society of Chemistry, 2014-11-21)

[EN] Oil is nowadays the main energy source and this prevalent position most probably will continue in the next decades. This situation is largely due to the degree of maturity that has been achieved in oil refining and ...
