Autor: | Tejedor, David CSIC ORCID CVN ; Delgado-Hernández, Samuel CSIC ORCID; Colella, Lucía; García-Tellado, Fernando CSIC ORCID | Palabras clave: | Acetone cyanohydrin DABCO Hydrocyanation Organocatalysis Terminal alkynes |
Fecha de publicación: | 27-nov-2019 | Editor: | Wiley-VCH | Citación: | Chemistry - A European Journal 25(66): 15046-15049 (2019) | Resumen: | A universal, practical and scalable organocatalytic hydrocyanation manifold to provide ß¿substituted acrylonitriles bearing an electron¿withdrawing functionality has been implemented. The catalytic manifold operates under the reactivity generation principle ¿a good nucleophile generates a strong base¿, and it uses 1,4¿diazabicyclo[2.2.2]octane (DABCO) as the catalyst, activated terminal alkynes as substrates and acetone cyanohydrin as the cyanide source. The acrylonitriles obtained as E,Z mixtures are straightforwardly resolved by simple flash chromatography delivering the pure isomers in preparative amounts. | Versión del editor: | https://doi.org/10.1002/chem.201903402 | URI: | http://hdl.handle.net/10261/202803 | DOI: | 10.1002/chem.201903402 | Identificadores: | doi: 10.1002/chem.201903402 e-issn: 1521-3765 issn: 0947-6539 |
