A Simple Entry to the 5,8-Disubstituted Indolizidine Skeleton via Hetero Diels-Alder Reaction
Autor: Juan Francisco Rodríguez-Caro, María M. Afonso, José Antonio Palenzuela
Publikováno v: Molecules, Vol 28, Iss 21, p 7316 (2023)
The 5,8-disubstituted indolizidines are the largest family of indolizidines isolated from the skin of amphibians. These compounds exhibit interesting biological activities such as noncompetitive blockers of nicotinic receptors. In this paper, we pres

Recent Advances in the Synthesis and Reactivity of Vinylallenes
Autor: María M. Afonso, Jose Antonio Palenzuela
Publikováno v: Current Organic Chemistry. 23:3004-3026
Vinylallenes have been synthesized and used as reagents for many years. However, the number of reviews covering the advances in the chemistry of vinylallenes are scarce. Most of the information lies in general reviews about allenes or in reviews dedi

Carbon dots as temperature nanosensors in the physiological range
Autor: M.A. Hernández-Rodríguez, Inocencio R. Martín, J. Antonio Palenzuela, K. Soler-Carracedo, María M. Afonso
Publikováno v: Journal of Luminescence. 196:313-315
This work shows the utility of the carbon dots, prepared from candle shoot, as promising candidates for nanothermometry devices based on temperature dependence of their emission lifetimes and of the changes of the full width at half maximum of the em

Determination of phthalates in beverages using multiwalled carbon nanotubes dispersive solid-phase extraction before HPLC-MS
Autor: María M. Afonso, Javier Hernández-Borges, Javier González-Sálamo, Miguel Ángel Rodríguez-Delgado
Publikováno v: Journal of separation science. 41(12)
A microdispersive solid-phase extraction method has been developed using multiwalled carbon nanotubes of 110-170 nm diameter and 5-9 μm length for the extraction of a group of nine phthalic acid esters (i.e., bis(2-methoxyethyl) phthalate, bis-2-eth

Evaluation of two molecularly imprinted polymers for the solid-phase extraction of natural, synthetic and mycoestrogens from environmental water samples before liquid chromatography with mass spectrometry
Autor: Bárbara Socas-Rodríguez, Javier González-Sálamo, Miguel Ángel Rodríguez-Delgado, Javier Hernández-Borges, María M. Afonso
Publikováno v: Journal of Separation Science. 38:2692-2699
In this work, we have compared the selectivity of two commercial molecularly imprinted polymers (AFFINIMIP®SPE Estrogens and AFFINIMIP®SPE Zearalenone) for the extraction of 12 estrogenic compounds of interest (i.e. 17α-estradiol, 17β-estradiol,

Issue 18
Molecules, Vol 24, Iss 18, p 3382 (2019)
In this work, we studied carbon paste electrodes (CPEs) with two kinds of binders: mineral oil or ionic liquids (IL) derived from N-substituted octyl pyridinium bis(trifluoromethylsulfonyl)imide with the substituents H-, CH3-, CN- and CF3-. The work
