24 p, 966.5 KB Enantioenriched Quaternary α-Pentafluoroethyl Derivatives of Alkyl 1-Indanone-2-Carboxylates / Granados Toda, Albert (Universitat Autònoma de Barcelona. Departament de Química) ; Ballesteros, Anna (Universitat Autònoma de Barcelona. Departament de Química) ; Vallribera Massó, Adelina (Universitat Autònoma de Barcelona. Departament de Química)
An electrophilic enantioselective catalytic method for the α-pentafluoroethylation of 3-oxoesters is described. Under the use of La(OTf)3 in combination with a (S,R)-indanyl-pybox ligand, good results in terms of yield and enantioselectivities were achieved (up to 89% ee). [...]

15 p, 1.3 MB Fluorous l -Carbidopa Precursors : Highly Enantioselective Synthesis and Computational Prediction of Bioactivity / Granados Toda, Albert (Universitat Autònoma de Barcelona. Departament de Química) ; Olmo, Anna del (Universitat Autònoma de Barcelona. Departament de Química) ; Peccati, Francesca (Universitat Autònoma de Barcelona. Departament de Química) ; Billard, Thierry (Université Claude Bernard-Lyon. Institute of Chemistry and Biochemistry) ; Sodupe Roure, Mariona (Universitat Autònoma de Barcelona. Departament de Química) ; Vallribera Massó, Adelina (Universitat Autònoma de Barcelona. Departament de Química)
New fluorous enantiopure (S)-α-aminated β-keto esters were prepared through a highly enantioselective electrophilic α-amination step in the presence of europium triflate and (R,R)-phenyl-pybox. These compounds are precursors of fluorinated analogues of l-carbidopa, which is known to inhibit DOPA decarboxylase (DDC), a key protein in Parkinson's disease. [...]

8 p, 1.0 MB Net-clipping : an approach to deduce the topology of metal-organic frameworks built with zigzag ligands / Ortín-Rubio, Borja (Institut Català de Nanociència i Nanotecnologia) ; Ghasempour, Hosein (Tarbiat Modares University. Department of Chemistry) ; Guillerm, Vincent (Institut Català de Nanociència i Nanotecnologia) ; Morsali, Ali (Tarbiat Modares University. Department of Chemistry) ; Juanhuix, Judith (ALBA Laboratori de Llum de Sincrotró) ; Imaz, Inhar (Institut Català de Nanociència i Nanotecnologia) ; Maspoch Comamala, Daniel (Institut Català de Nanociència i Nanotecnologia)
Herein we propose a new approach for deducing the topology of metal-organic frameworks (MOFs) assembled from organic ligands of low symmetry, which we call net-clipping. It is based on the construction of nets by rational deconstruction of edge-transitive nets comprising higher-connected molecular building blocks (MBBs). [...]

17 p, 1.2 MB Postsynthetic Selective Ligand Cleavage by Solid-Gas Phase Ozonolysis Fuses Micropores into Mesopores in Metal-Organic Frameworks / Guillerm, Vincent (Institut Català de Nanociència i Nanotecnologia) ; Xu, Heng (Institut Català de Nanociència i Nanotecnologia) ; Albalad, Jorge (Institut Català de Nanociència i Nanotecnologia) ; Imaz, Inhar (Institut Català de Nanociència i Nanotecnologia) ; Maspoch Comamala, Daniel (Institut Català de Nanociència i Nanotecnologia)
Herein we report a novel, ozone-based method for postsynthetic generation of mesoporosity in metal-organic frameworks (MOFs). By carefully selecting mixed-ligand Zr-fcu-MOFs based on organic ligand pairs in which one ligand has ozone-cleavable olefin bonds and the other ligand is ozone-resistant, we were able to selectively break the cleavable ligand via ozonolysis to trigger fusion of micropores into mesopores within the MOF framework. [...]

6 p, 767.9 KB Zigzag ligands for transversal design in reticular chemistry : unveiling new structural opportunities for metal-organic frameworks / Guillerm, Vincent (Institut Català de Nanociència i Nanotecnologia) ; Grancha, Thais (Institut Català de Nanociència i Nanotecnologia) ; Imaz, Inhar (Institut Català de Nanociència i Nanotecnologia) ; Juanhuix, Judith (ALBA Laboratori de Llum de Sincrotró) ; Maspoch Comamala, Daniel (Institut Català de Nanociència i Nanotecnologia)
Herein we describe the topological influence of zigzag ligands in the assembly of Zr(IV) metal-organic frameworks (MOFs). Through a transversal design strategy using reticular chemistry, we were able to synthesize a family of isoreticular Zr(IV)-based MOFs exhibiting the bcu - rather than the fcu - topology. [...]
