Llopis, Sebastian;Velty, Alexandra;Diaz, Urbano research published 《 Active Base Hybrid Organosilica Materials based on Pyrrolidine Builder Units for Fine Chemicals Production》, the research content is summarized as follows. The catalytic activity of “pyrrolidine type” fragments included or anchored in the mesoporous silica supports or polymeric frameworks have been fully reported for enantioselective transformation. Nevertheless, low attention was focused on their catalytic abilities to perform base-catalyzed reaction. Accordingly, hybrid materials including pyrrolidine fragments in the mesoporous silica supports were prepared following different synthesis methods, such as micellar and fluoride sol-gel routes in absence of structural directing agents. Their great catalytic performance was explored for various base-catalyzed reactions to the formation of C-C bond through Knoevenagel, Claisen-Schmidt and Henry condensations under microwave irradiation The benefits of microwave irradiation combined with suitable catalytic properties of pyrrolidine hybrid materials with strong base sites and high accessibility to active centers, allowed carrying out successfully base-catalyzed condensation reactions for the production of fine chems. Moreover, the hybrid catalyst exhibited high selectivity and good stability over different catalytic cycles contributing to environmental sustainability.

Lou, Yazhou;Wei, Junqiang;Li, Mingfeng;Zhu, Ye research published 《 Distal Ionic Substrate-Catalyst Interactions Enable Long-Range Stereocontrol: Access to Remote Quaternary Stereocenters through a Desymmetrizing Suzuki-Miyaura Reaction》, the research content is summarized as follows. Spatial distancing of a substrate’s reactive group and nonreactive catalyst-binding group from its pro-stereogenic element presents substantial hurdles in asym. catalysis. In this context, we report a desymmetrizing Suzuki-Miyaura reaction that establishes chirality at a remote quaternary carbon. The anionic, chiral catalyst exerts stereocontrol through electrostatic steering of substrates, even as the substrate’s reactive group and charged catalyst-binding group become increasingly distanced. This study demonstrates that precise long-range stereocontrol is achievable by engaging ionic substrate-ligand interactions at a distal position.

B. research published 《 Design, synthesis and antifungal activity of new schiff bases bearing 2-aminothiophene derivatives obtained by molecular simplification》, the research content is summarized as follows. Seventeen Schiff bases bearing 2-aminothiophene derivatives I (R = 3-NO₂C₆H₄, 4-ClC₆H₄, 4-nitro-1H-indol-3-yl, etc.) were designed and synthesized using mol. simplification. The resulting compounds were evaluated for their in vitro antifungal activity against dermatophytes. Prediction of their druglikeness and pharmacokinetic properties, establishment of their structure-activity relationships (SAR), and cytotoxic evaluation of the most active compounds were performed. Using an eco-friendly procedure, microwave assisted synthesis resulted in compounds in good yields (35-85%). Compounds I presented good druglikeness and pharmacokinetic profiles and no cytotoxicity for any cell line tested up to 100μM. The compounds presenting the best antifungal profiles were I (R = 2,6-(Cl)₂C₆H₃, 2-NO₂C₆H₄, 3-NO₂C₆H₄, 4-NO₂C₆H₄, 3,4,5-(MeO)₃C₆H₂, C₆H₅, 4-BrC₆H₄, 4-nitro-1H-indol-3-yl) with more than one min. inhibitory concentration (MIC) value occurring between 16-64μg mL^-1, thus, in some cases better than the reference drug (fluconazole). SAR testing indicated that the presence of halogens and nitro substituents increases antifungal activity. Taken together, the results demonstrate that 2-aminothiophene derivatives are promising lead compounds for the development of antifungal drugs.

Liu, Chenguang;Wang, Mingyang;Xu, Yihan;Li, Yibiao;Liu, Qiang research published 《 Manganese-Catalyzed Asymmetric Hydrogenation of 3H-Indoles》, the research content is summarized as follows. A Mn-catalyzed AH of 3H-indoles e.g., 2,3,3-trimethyl-3H-indole with excellent yields and enantioselectivities was reported.

The reaction could proceed with catalyst loadings at the ppm (ppm) level with an exceptional turnover number of 72 350. This is the highest value yet reported for an earth-abundant metal-catalyzed AH reaction.

Liu, Hong;Li, Kai;Huang, Shengli;Yan, Hailong research published 《 An Isolable Vinylidene ortho-Quinone Methide: Synthesis, Structure and Reactivity》, the research content is summarized as follows. Commonly, an elusive intermediate is generated from a precursor and then trapped and consumed in a reaction. Vinylidene ortho-quinone methides (VQMs) have been demonstrated as transient axially chiral intermediates in asym. catalysis due to their orthogonal π-bonds forming an allene motif. The current understanding of VQMs is primarily based on time-resolved absorption, trapping experiments and computational studies. Herein, the authors report the first isolation and comprehensive characterization of a VQM, including crystallog. anal. The disturbed aromaticity of the VQM led to its high reactivity as an electrophile or a 4π-component capable of asym. dearomatization of an electron-deficient Ph group. Notably, the VQM could be isolated in enantiomerically enriched form, and the subsequent transformation was stereospecific, indicating that the generation of the VQM was involved in the enantiodetermining step. This study paves the way for the direct application of VQMs as starting materials.
