Organocatalytic Asymmetric Addition of Naphthols and Electron-Rich Phenols to Isatin-Derived Ketimines: Highly Enantioselective Construction of Tetrasubstituted Stereocenters

Montesinos Magraner, Marc; Vila, Carlos; Cantón, Rubén; Blay, Gonzalo; Fernández, Isabel; Muñoz Roca, María del Carmen; Pedro, José R. (Wiley, 2015)

A quinine-derived thiourea organocatalyst promoted the highly enantioselective addition of naphthols and activated phenols to ketimines derived from isatins. The reaction afforded chiral 3-amino-2-oxindoles with a ...
Organocatalytic Enantioselective Alkylation of Pyrazol-3-ones with Isatin-Derived Ketimines: Stereocontrolled Construction of Vicinal Tetrasubstituted Stereocenters

Amr, Fares Ibrahim; Vila, Carlos; Blay, Gonzalo; Muñoz Roca, María del Carmen; Pedro, José R. (Wiley, 2016-05-19)

A quinine-derived thiourea catalysed the enantioselective addition of 4-substituted pyrazolones to isatin-derived ketimines, providing a variety of aminooxindole-pyrazolone adducts containing congested vicinal ...
Organocatalytic Enantioselective Friedel-Crafts Aminoalkylation of Indoles in the Carbocyclic Ring

Montesinos Magraner, Marc; Vila, Carlos; Rendón Patiño, Alejandra; Blay, Gonzalo; Fernández, Isabel; Muñoz Roca, María del Carmen; Pedro, José R. (American Chemical Society, 2016)

The first general catalytic method for the, so far elusive, enantioselective Friedel−Crafts functionalization of indoles in the carbocyclic ring is presented. This transformation contrasts with the usual tendency of these ...
Organocatalytic Enantioselective Functionalization of Hydroxyquinolines through an Aza-Friedel-Crafts Alkylation with Isatin-derived Ketimines

Vila, C.; Rendón-Patiño, A.; Montesinos-Magraner, M.; Blay, G.; Muñoz Roca, María Del Carmen; Pedro, J.R. (John Wiley & Sons, 2018-03-01)

[EN] A highly enantioselective addition of hydroxyquinolines to isatin-derived ketimines has been realized using a quinine-derived thiourea organocatalyst. The reaction affords chiral 3-amino-2-oxindoles bearing a quinoline ...
Organocatalytic Enantioselective Synthesis of Pyrazoles Bearing a Quaternary Stereocenter

Vila, Carlos; Amr, Fares Ibrahim; Blay, Gonzalo; Muñoz Roca, María del Carmen; Pedro, José R. (Wiley, 2016-05-20)

An efficient one-pot asymmetric synthesis of pyrazoles bearing a chiral quaternary stereocenter has been developed. Quinine-derived thiourea catalyzed the enantioselective addition of pyrazolones to isatin-derived ketimines, ...
