SeRMN contribution to Symmetry 2017 Conference


Some of the SeRMN staff  presented our last research work about chirality at The first International Conference on Symmetry, Symmetry 2017, that took place from16th to 18th October in Barcelona. Find below a summary of our contribution.

Míriam Pérez-Trujillo presented a lecture entitled: “Chiral Recognition by Dissolution Dynamic Nuclear Polarization NMR Spectroscopy

Abstract: The recognition of enantiomeric molecules by chemical analytical techniques is still a challenge. A method based on d-DNP (dissolution dynamic nuclear polarization) NMR spectroscopy to study chiral recognition was described for the first time [1]. DNP allows boosting NMR sensitivity by several orders of magnitude, overcoming one of the main limitations of NMR spectroscopy [2]. A method integrating d-DNP and 13C NMR-aided enantiodifferentiation using chiral solvating agents (CSA) was developed, in which only the chiral analyte was hyperpolarized and selectively observed by NMR. The described method enhances the sensitivity of the conventional NMR-based procedure [3] and lightens the common problem of signal overlapping between analyte and CSA. As proof on concept, racemic metabolite 13C-labeled DL-methionine was enantiodifferentiated by a single-scan 13C NMR experiment. This method entails a step forward in the chiral recognition of small molecules by NMR spectroscopy; it opens new possibilities in situations where the sensitivity is limited, for example, when low analyte concentration available or when measurement of an insensitive nucleus required. The advantages and current limitations of the method, as well as future perspectives, are discussed.

SeRMN at the SMASH NMR 2016 Conference

Some of our last research works has been presented at the annual meeting of the SmallMolecule NMR Conference (SMASH) that has been taken place in La Jolla (USA) from 11thto 14thSeptember 2016.

Teodor Parella presented two posters.
“In situ determination of 1DCH and 2DHH RDCs from a single 1JCH/2JHH -resolved NMR measurement” of Núria Marcó García, Roberto R. Gil and Teodor Parella.

Abstract: A fast RDC-assisted strategy involving the simultaneous determination of isotropic (scalar) and anisotropic (total) interactions is reported. The concerted use of individual 1DCH for all CHn multiplicities and 2DHH obtained from a single 1JCH/2JHH-resolved NMR spectrum offers an unambiguous assignment of diastereotopic protons and an efficient discrimination between all eight possible diastereoisomeric structures of strychnine which contains six stereocenters.

“Pure shift NMR covariance” of André Fredi, Pau Nolis, Carlos Cobas, Gary E. Martin, Teodor Parella.

Abstract: The development of novel experimental strategies to significantly enhance signal resolution by broadband homodecoupling is a current topic of high interest in 1H NMR spectroscopy . A number of different building blocks have been implemented into 1D and 2D homo- and heteronuclear experiments in order to provide resolution-enhanced pure chemical shift 1H NMR spectra, where signals appear collapsed to singlets. On the other hand, Covariance processing methods have been used to generate challenging NMR spectral representations . We present here the first attempts towards a general solution to generate Pure Shift NMR spectra by using Generalized Indirect Covariance (psGIC) co-processing3,4 . The current strategy is based on the calculation of a new 2D psGIC spectrum from the combination of a parent homo- or heteronuclear spectrum and a reference 2D F1-homodecoupled 1H- 1H correlation spectrum only showing diagonal cross-peaks (DIAG), which share a common 1H frequency dimension. Using psGIC, the F1 dimension in the DIAG spectrum is transferred to the F2 dimension of the parent spectrum, thus generating a new pure shift 2D spectrum

André Fredi’s oral presentation at 8th GERMN / 5th Iberian NMR Meeting

André Fredi made an oral presentation at the 8th GERMN / 5th Iberian NMR Meeting (GERMN 2016) held in Valencia, Spain from 27th to 29th June 2016.

In his presentation, that was titled  Exploring the use of Generalized Indirect Covariance to reconstruct Pure Shift NMR spectra: Current Pros and Cons”, André explained how to make pure spectra shift from Generalized Indirect IMG-20160628-WA0028Covariance processing (psGIC). This new method is basically a new way to get “synthetic” pure shift spectra without the need to purchase a pure shift spectrum in the spectrometer and without the penalties that pure-shift experiments cause.

André has been working as a Ph.D. candidate at the Department of Chemistry and SeRMN under the direction of Dr. Teodor Parella and Dr. Pau Nolis since November 2014, when he enrolled in the Department of Chemistry doctoral program at Universitat Autònoma de Barcelona with a fellowship from CNPq-Brazil. He is currently in his second year and expects to defend the doctoral thesis on 2017/2018.

PhD Thesis by Laura Castañar: Pulse Programs and Data Set Examples

Development and application of modern pure shift NMR techniques and improved HSQC/HSQMBC experiments


In the following links one can find Data Set Examples of each Publication presented in the Thesis Work, as well as the corresponding Pulse Program Code for Bruker. All 2D spectra have been previously phased and 2ii, 2ir, and 2ri files removed, otherwise data sets would be too big.
