Our last publication at the J. Am. Chem. Soc. already on-line

11/10/2018
This recent article at the Journal of the American Chemical Society is already available as just accepted manuscript

We are very glad to announce the publication of our latest paper at the Journal of the American Chemical Society, entitled "Gold(I)–catalyzed enantioselective annulations between allenes and alkene-tethered oxime ethers: A straight entry to highly substituted piperidines and aza-bridged medium-sized carbocycles", by D. C. Marcote, I. Varela, J. Fernandez-Casado, J. L. Mascareñas and F. López . In which, we report a gold-catalyzed annulation strategy that allows a straightforward assembly of piperidines and piperidine-containing aza-bridged products from readily available alkene-tethered oxime ethers (or esters) and N-allenamides.

ACS Catalysis. Third over the last 40 days... good job guys!!

07/10/2018
We are very glad to announce we got our third consecutive publication accepted at ACS Catalysis, in just fourty days.

Already available on-line our last publication at ACS catalysis by D. F. Fernández, C. A. B. Rodrigues, M. Calvelo, M. Gulías, J. L. Mascareñas and F. López, entitled "Iridium(I)-Catalyzed Intramolecular Cycloisomerization of Enynes: Scope and Mechanistic Course"

Abstract:
We report an Ir(I)-catalyzed cycloisomerization methodology that provides access to carbocyclic systems bearing exo-alkene moieties from alkynyl-equipped acyclic precursors. The method relies on the C-H activation of olefinic and (het-ero)aromatic C(sp2)–H bonds, followed by an exo-cyclization to a tethered alkyne, and provides interesting cyclic diene products that are amenable of further elaboration. Importantly, DFT calculations suggests that, in contrast to related hydrocarbonations of alkenes in which either migratory insertions or C-C reductive eliminations have been suggested to be rate determining, in our reac-tions, the energetic barrier of these steps is lower than that of the previous C–H activation.

Our last publication at ACS Catalysis among the ACS editor’s choice articles

Our latest letter to ACS Catalysis selected from acrossall ACS journals by ACS editors for its potential broad public interest

"Intracellular deprotection reactions mediated by palladium complexes equipped with designed phosphine ligands", authored by M. Martínez-Calvo, J. R. Couceiro, P. Destito, J. Rodriguez, J. Mosquera and J. L. Mascareñas, is our latest paper at ACS Catalysis.

Abstract:
Discrete palladium (II) complexes featuring purposely designed phosphine ligands can promote depropargylation and deallylation reactions in cell lysates. The performance of these complexes is superior to that of other palladium sources, which apparently are rapidly deactivated in such hostile complex media. This good balance between reactiv-ity and stability allows the use of these discrete phosphine palladium complexes in living mammalian cells, whereby they can mediate similar transformations. The presence of a phosphine ligand in the coordination sphere of palladi-um also provides for the introduction of targeting groups, such as hydrophobic phosphonium moieties, which facili-tate the accumulation of the complexes in mitochondria.

Already available in ASAP our last letter to ACS Catalysis

"Enantioselective Palladium-Catalyzed [3C + 2C] and [4C + 3C] Intramolecular Cycloadditions of Alkylidenecyclopropanes" by F. Verdugo, L. Villarino, J. Durán, M. Gulías, J. L. Mascareñas and F. López is already available on-line

ABSTRACT: We report a highly enantioselective [3C + 2C] intramolecular cycloaddition of alkylidenecyclopropanes (ACPs) and alkenes. The best results are obtained by using sterically demanding chiral phosphoramidite ligands derived from Vapol. Moreover, we also show that related, but less bulky, phosphoramidites can also lead to very effective [4C + 3C] cycloadditions when dienes, instead of alkenes, are used as reacting partners. The reactions provide a practical, simple, and selective access to optically active, synthetically appealing 5,5- and 5,7-bicyclic systems.
