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 Friedel-Crafts Alkylation of 1-Naphthol Derivatives and Activated Phenols with Ethyl Trifluoropyruvate

Montesinos Magraner, Marc; Vila, Carlos; Blay, Gonzalo; Fernández, Isabel; Muñoz Roca, María del Carmen; Pedro, José R. (Wiley, 2015-10-12)

An organocatalytic enantioselective Friedel–Crafts alkylation of a series of substituted 1- naphthol derivatives and activated phenols with ethyl trifluoropyruvate, catalyzed by a quinine-derived squaramide, is presented. ...
