  • Interplay of diamides and rare earth metals: Specific molecular spaces and catalytic activity

    Kumagai N., Shibasaki M., Designed Molecular Space in Material Science and Catalysis, 2018.01

    　View Summary

    A catalytic system comprising functionalized small diamides and rare earth metals (REs) exerts intriguing catalytic properties that are dictated by dynamic construction of flexible molecular spaces. The dynamic interaction of diamides and REs is characterized by broad applicability to distinct reaction systems as well as notable switchable catalysis. Structural modification of the diamide allows for enhanced intermolecular interactions to afford a self-assembled solid-phase catalyst with a specific molecular space that engages in heterogeneous asymmetric catalysis with a continuous-flow platform.

  • Chiral Bimetallic Lewis Acids

    Shibasaki M., Kumagai N., Topics in Organometallic Chemistry, 2018

    　View Summary

    Here, we review the utility of chiral bimetallic (multimetallic) Lewis acidic complexes in catalytic asymmetric transformations. Bimetallic complexes are endowed with dual catalytic functions that synergistically activate multiple substrates and functionalities. This cooperative activation mode is particularly effective for activating low reactivity substrates in a highly stereoselective manner without the aid of stoichiometric activating reagents. The privileged bimetallic catalysts presented here highlight the importance of catalyst design in the development of widely applicable catalytic systems.

  • DiQuinoline-MonoQuinazoline: A Flat Proton Binder and its Application as a Polyaromatic Hydrocarbon Scavenger and G4 Ligand

    Karimata T., Xu W., Kumagai N.

    Chemistry - A European Journal  2025

    ISSN  09476539

    　View Summary

    A new miniaturized framework for graphitic material featuring three neighboring pyridinic nitrogen atoms is disclosed. The quinoline/quinazoline hybridized pseudo trimeric macrocycle, DiQuinoline(Q)-MonoQuinazolines(Qz), Q2Qz1, was readily synthesized from the key macrocyclic amide precursor in a modular fashion. Its central cavity strongly captures a proton, and the thus-formed positively charged, highly planar architecture exhibits supramolecular complexation through π-interactions. Q2Qz1, with its unique properties, was applied as a scavenger for toxic polyaromatic hydrocarbons and as a G-quartet ligand for potential therapeutic agent for cancer chemotherapy.

  • Recent Advances in Quinoline-Based Macrocycles: Synthesis, Properties, and Applications in Catalytic Reactions

    Xu W., Kumagai N.

    Synthesis (Germany) 56 ( 11 ) 1765 - 1774 2024.05

    ISSN  00397881

    　View Summary

    Macrocyclic compounds exhibit unique properties due to their large ring-shaped structures, which have captivated chemists in recent decades. These molecules exert specific functions in various applicable fields, such as chemistry, materials science, and biology. Crown ethers, calixarenes, and porphyrinoids, which contain several ether/phenol/pyrrole subunits, represent these molecular categories with unparalleled functional diversity. In contrast, quinoline-based macrocycles comprising the quinoline unit as a key element to construct specific ring shapes have received limited attention. In this minireview, we summarize the recent advances in oligoquinoline macrocycles TriQuinoline (TQ), oxa-TriQuinoline (o-TQ), TEtraQuinoline (TEQ), and other bridged quinoline-based macrocycles. Emphasis is placed on the synthesis, structure, and application of these molecules in organometallic and supramolecular chemistry, which may guide new molecular designs in the quinoline-based macrocycle family. 1 Introduction 2 Quinoline-Based Macrocycles 2.1 TriQuinoline (TQ) 2.2 Oxa-TriQuinoline (o-TQ) 2.3 TEtraQuinoline (TEQ) 2.4 Larger Quinoline-Based Macrocycles with Bridges 3 Conclusion.

  • In2Q2: A New Entry of 16-Membered Tetraazamacrocycle Concatenating Indole and Quinoline Units

    Kihara K., Kobayashi T., Xu W., Kumagai N.

    Chemistry - A European Journal 30 ( 25 )  2024.05

    ISSN  09476539

    　View Summary

    A new family of 16-membered macrocycles comprising two indole (In) and two quinoline (Q) units, coined In2Q2, was synthesized. Each unit is diagonally located and concatenated in a head-to-tail fashion, furnishing a non-flat saddle-shaped architecture with C2 symmetry. The synthetic protocol utilizing macrocyclic diamide as a pivotal precursor allowed us to access a series of In2Q2 derivatives bearing various substituents on the periphery. The In2Q2 derivatives and their Zn2+ complexes were emissive in both solution phase and solid state. While the entire architecture of In2Q2 is similar to that of quinoline tetramer TEtraQuinoline, a couple of contrasting physicochemical properties were revealed.

  • Chemoselective Catalytic Dehydrogenation of Benzylic Amines Driven by the TEtraQuinoline/FeCl<inf>2</inf> Complex

    Nishiwaki M., Xu W., Kumagai N.

    Asian Journal of Organic Chemistry (Asian Journal of Organic Chemistry)  12 ( 9 )  2023.09

    ISSN  21935807

    　View Summary

    A chemoselective dehydrogenation protocol for benzylic amines catalyzed by the TEtraQuinoline (TEQ)/FeCl2 complex is described. In combination with 2 equiv of tert-butyl hydroperoxide, as little as 0.1 mol% of catalyst loading was sufficient to convert primary and secondary benzylic amines to the corresponding imines and dimerized imines, respectively. Subsequent hydrolysis of the imines allowed for removal of the benzyl group on the nitrogen atom. Nonaromatic carbon-carbon multiple bonds and the O-Bn group remained intact in the present protocol, providing a complementary deprotection procedure to reductive removal conditions exerted by Pd catalysis.

  • Oxa-TriQuinoline: A New Entry to Aza-Oxa-Crown Architectures**

    Kobayashi T., Kumagai N.

    Angewandte Chemie - International Edition (Angewandte Chemie - International Edition)  62 ( 32 )  2023.08

    ISSN  14337851

    　View Summary

    A new 15-membered-macrocyclic molecular entity, oxa-TriQuinoline (o-TQ), was designed and synthesized. In o-TQ, three oxygen atoms were joined onto three quinoline units at the 2- and 8-positions in a head-to-tail fashion by three-fold SNAr reactions, giving rise to the characteristic N3O3 aza-oxa-crown architecture. o-TQ can serve as a new tridentate nitrogen ligand to capture a CuI cation and adopt a bowl shape, before supramolecular complexation with corannulene and [12]cycloparaphenylene (CPP) occurs through π–π and CH–π interactions. In the presence of the CuI cation, the non-emissive o-TQ becomes a highly emissive material in the solid state, whereby the emission wavelengths depend on the ancillary ligand on the CuI cation. The o-TQ/CuI complex is able to promote carbene catalysis to provide a range of enamines with a gem-difluorinated terminus.
