Autor: Ignacio Rodríguez-García, J. Enrique Oltra, Laura Pozo Morales, Esther Roldan-Molina, Marta García-Ocaña, Natalia M. Padial, Juan Muñoz-Bascón, Antonio Rosales
Publikováno v: European Journal of Organic Chemistry. 2015:4567-4591
The vast range of reactions mediated by titanocene monochloride (Cp2TiCl, the Nugent reagent) in organic synthetic chemistry is reviewed. The power of the Nugent reagent in organic chemistry is demonstrated by its ability to promote and/or catalyse s

Autor: Juan Muñoz-Bascón, Mayra A. Castañeda, J. Enrique Oltra, Ignacio Rodríguez-García, Natalia M. Padial, Esther Roldan-Molina, Antonio Rosales, Andreas Gansäuer
Publikováno v: The Journal of Organic Chemistry. 79:7672-7676
An experimental study on the role played by each of the reagents involved in the selective reduction of aromatic ketones in aqueous medium is reported. In this reaction, the reduction of aromatic ketones is mediated by Cp2TiCl. Moreover, the presence

Autor: Antonio Rosales, Nazaret Rivas-Bascón, Juan Muñoz-Bascón, Natalia M. Padial, Esther Roldan-Molina, Ignacio Rodríguez-García, Roman Rodríguez-Maecker, J. Enrique Oltra
Publikováno v: The Journal of organic chemistry. 80(3)
A bioinspired and sustainable procedure for the straightforward synthesis of (±)-aureol has been achieved in eight steps (14% overall yield) from epoxyfarnesol. The key steps are the titanocene(III)-catalyzed radical cascade cyclization of an epoxyf
