title: Design of fast redox-controlled self-immolative selenium-based cysteine surrogates

description: The self-immolation of N-selenoethyl cysteine derivatives into cysteine
 exhibits a strong Thorpe-Ingold effect. Notably, the gem-dimethyl
 substitution alpha to the selenium atom achieved rate accelerations up to
 252-fold, enabling Cys unmasking through C-N bond cleavage within minutes.
 These investigations offer valuable insights into the mechanism of
 selenoethyl arm breakdown and new redox-sensitive Cys surrogates.

 [https://doi.org/10.5061/dryad.2bvq83c2q](https://doi.org/10.5061/dryad.2bvq83c2q) ## Description of the data and file structure We have submitted our nuclear magnetic resonance (NMR) data for structure elucidation of all the chemical intermediates involved in the synthesis of Fmoc-MeSetCys-OH and Fmoc-Me2SetCys-OH (FID NMR.7z). This dataset includes raw NMR data files for all NMR spectra presented in this manuscript. Raw data files are stored in subfolders corresponding to compound name. Each numerically named subfolder represents the data for a single spectrum and can be directly opened with the Bruker’s TopSpin software mentioned in the following “Usage Notes.” All these folders should contain all the required information to access the data and interactively view the NMR spectra. A more detailed list of the files is provided at the end of this README file. ## Usage notes For viewing NMR raw data, the Bruker’s TopSpin 4.4.1 release software package can be used. ### Files and variables #### File: FID NMR.7z **Description:** This compressed archive contains sixteen folders. Each fold contains the raw NMR data of all the chemical intermediates involved in the synthesis of Fmoc-MeSetCys-OH and Fmoc-Me2SetCys-OH.  The file names within the folder adhere to the following naming convention: "NMR CompoundName". CompoundName: Refers to the compound being analyzed. In each file are gathered all the NMR experiments required for the structure elucidation (1H, 13C Jmod, COSY, HSQC) and are named according to the corresponding experiment.
