Asymmetric transformations under chiral bronsted acid catalysis: (4+3) cycloaddition and allylboration of imines
Villar Arango, Laura (2017-05-19)La memoria recoge el estudio y desarrollo de diversas reacciones organocatalíticas enantioselectivas. Explorando, en primer lugar, la utilización de alenamidas como precursores de cationes oxaalílicos en la cicloadición ... -
Enantioselective Oxidative (4+3) Cycloadditions between Allenamides and Furans through Bifunctional Hydrogen-Bonding/Ion-Pairing Interactions
Villar Arango, Laura; Uria Pujana, Uxue ; Martinez, Jose I.; Prieto Aretxabaleta, Liher ; Reyes Martín, Efraim; Carrillo Fernández, María Luisa ; Vicario Hernando, José Luis (Wiley-VCH, 2017-07-03)BINOL-based N-trifluoromethanesulfonyl phosphoramides catalyze the enantioselective (4+3) cycloaddition between furans and oxyallyl cations, the latter being generated in situ by oxidation of allenamides. The chiral ... -
Kinetic Resolution of Secondary Allyl Boronates and Their Application in the Synthesis of Homoallylic Amines
Villar Arango, Laura; Orlov, Nikolai V.; Kondratyev, Nikolay S.; Uria Pujana, Uxue ; Vicario Hernando, José Luis ; Malkov, Andrei V. (Wiley-VCH, 2018-09-02)Highly enantioenriched, chromatographically-stable secondary allyl boronates featuring a 1,1,2,2-tetraethyl-1,2-ethanediol fragment (Epin) were obtained by kinetic resolution of their racemic mixtures. The Epin group at ...
