    Circularly Polarized Luminescence from Simple Organic Molecules
    (Chemistry: a european journal, 2015) Márquez Sánchez-Carnerero, Esther María; Rodríguez Agarrabeitia, Antonia; Moreno Jiménez, Florencio; Lora Maroto, Beatriz; Muller, Gilles; Ortiz García, María Josefa; Moya Cerero, Santiago De La
    This article aims to show the identity of “circularly polarized luminescent active simple organic molecules” as a new concept in organic chemistry due to the potential interest of these molecules, as availed by the exponentially growing number of research articles related to them. In particular, it describes and highlights the interest and difficulty in developing chiral simple (small and non-aggregated) organic molecules able to emit left- or right-circularly polarized light efficiently, the efforts realized up to now to reach this challenging objective, and the most significant milestones achieved to date. General guidelines for the preparation of these interesting molecules are also presented.

    Preparation of dipyrrins from F-BODIPYs by treatment with methanesulfonic acids
    (RSC Advances, 2015) Urieta Mora, Javier; Lora Maroto, Beatriz; Moreno Jiménez, Florencio; Rodríguez Agarrabeitia, Antonia; Ortiz García, María Josefa; Moya Cerero, Santiago De La
    An alternative metal-free soft procedure for the preparation of dipyrrins from F-BODIPYs is reported. The new method makes possible to obtain certain dipyrrin derivatives that were unaccessible from F-BODIPYs to date. To demonstrate the ability of the new procedure, dipyrrins having highly reactive groups, such as chloro, cyano or acetoxyl, have been easily obtained from the corresponding F-BODIPY, which shows the synthetic utility of the reported methodology.

    Speeding up heterogeneous catalysis with an improved highly reusable catalyst for the preparation of enantioenriched secondary alcohols
    (Reactive and Functional Polymers, 2017) Sánchez Carnerero, Esther M. Márquez; Sandoval Torrientes, Rafael; Urieta Mora, Javier; Moreno Jiménez, Florencio; Maroto, Beatriz Lora; Moya Cerero, Santiago De La
    A new catalytic heterogeneous system, very efficient and highly reusable, for the preparation of enantioenriched secondary alcohols through the addition of diethylzinc to benzaldehyde has been developed. This system is based on a chiral bis(hydroxyamide) ligand supported on crosslinked polystyrene. The catalyst has been shown to be very efficient, leading to the corresponding secondary alcohol with an enantiomeric excess of 93% in a time as short as 2 h and using just 4% of the heterogeneous catalyst and just 1.5 equivalents of the organozinc reagent. We have demonstrated that the new catalyst is very stable and can be efficiently recycled with no decrease in yield or enantioselectivity. The presented system has an unquestionable interest for the potential transfer of the reaction to the industry by using catalytic fluidized-bed reactors.
