Abstract
A scalable endo-selective synthesis of 2,3,4,5-tetrasubstituted pyrrolidines via cycloaddition of nitroalkenes and azomethine ylides is reported using a P,N-type ferrocenyl ligand and [Cu(OTf)]2·C6H6. The robust method is tolerant of a wide range of functionalities, including rarely reported quaternary nitroalkene substitution and heteroaromatic and hindered ortho-substituted arenes on the azomethine ylide. Subsequent transformations highlight the utility of the method in the synthesis of densely functionalized small molecules suitable for fragment-based drug discovery and the cystic fibrosis C2-corrector clinical candidate ABBV-3221.

Abstract
In the manuscript, computational studies on the remote alkylation of 5-alkylfurfurals proceeding via formation of the corresponding trienamine intermediate are presented. By the means of density functional theory (DFT) calculations and the symmetry-adapted perturbation theory (SAPT) method, interesting insights into the mechanism of the reaction have been provided explaining the influence and contribution of different molecular interactions on the observed reactivity as well as on the enantio- and diastereoselectivity of the process. The studies have been extended to the thiophene analogue of the starting furfural derivative and the results obtained verified experimentally.

Abstract
In this work we have found that a BODIPY can be used as an electron withdrawing group for the activation of double bonds in asymmetric catalysis. The synthesis of cyclohexyl derivatives containing a BODIPY unit can easily be achieved via trienamine catalysis. This allows a new different asymmetric synthesis of BODIPY derivatives and opens the door to future transformation of this useful fluorophore. In addition, the Quantum Chemistry calculations and mechanistic studies provide insights into the role of BODIPY as an EWG.
