Simple dissymmetrical and asymmetrical Tröger's bases: Photophysical and structural characterization
(Royal Society of Chemistry, 2020-05)
Despite their continuously growing preparation and applications in the last decades, the photophysical properties of Tröger’s bases (TBs) with small substituents have not been analyzed. We synthetized three dissymmetrical ...
Synthesis of new cyano-substituted analogues of Tröger's bases from bromo-derivatives. A stereochemical dependence of long-range ( n J HH , n = 4, 5, and 6) proton-proton and proton-carbon ( n J CH , n = 1, 2, 3, 4, and 5) coupling constants of these compounds
(John Wiley & Sons Ltd, 2019-04)
A free-catalyst microwave-assisted cyanation of brominated Tröger´s base derivatives (2a-f) is reported. The procedure is simple, efficient and clean affording the nitrile compounds (3a-e, I) in very good yields. Complete ...
Uncovering the mechanism leading to the synthesis of symmetric and asymmetric Tröger's bases
(Wiley VCH Verlag, 2019-11)
Tröger´s bases have been attracting great interest due to their potential applications in nanoelectronics, supramolecular chemistry, molecular recognition, biological activity and auxiliaries for asymmetric synthesis. ...
Recientes usos del benzotriazol como auxiliar sintético en la obtención de diversos sistemas heterocíclicos.
(2011-10-14)
El presente trabajo se recoge una serie de resultados en los que se evalúa la efectividad del benzotriazol (BtH) como auxiliar en la síntesis de diversos sistemas heterocíclicos. Se pudo demostrar que su utilidad está ...

Long-range anisotropic effects in a V–shaped Tröger's base diformanilide: Conformational study by NMR assignment and DFT calculations
(Elsevier Science, 2018-04)
Herein we describe the synthesis and conformational analysis of a Tröger's base diformanilide whose distinctive NMR spectra was fully assigned via DFT calculations. The complexity of the spectra originated by the presence ...
The mechanism of Troger's base formation probed by electrospray ionization mass spectrometry
