The first synthesis of a pyrene-containing carbon nanoring, cyclo[12]-paraphenylene[2]-2,7-pyrenylene ([12,2]CPPyr), is described. Through a sequence of stepwise macrocyclization using Pd and Ni catalysts followed by aromatization of L-shaped cyclohexane units afforded a [12,2]CPPyr in five steps from commercially available compounds. The UV-vis absorption and fluorescence spectra as well as TD-DFT calculations clarified the unique photophysical and electronic properties of the [12,2]CPPyr.

Polarized Raman spectroscopy on topological semimetal Co3Sn2S2

Kenya Tanaka, Taishi Nishihara, Akira Takakura, Yasutomo Segawa, Kazunari Matsuda, Yuhei Miyauchi

Summary: In this study, polarized Raman spectroscopy was used to investigate the topological semimetal Co3Sn2S2. The results revealed that the Raman signals at low and high wave numbers are related to phonon modes with different symmetries. The high wave number A1g mode showed an asymmetric peak feature, indicating a Fano resonance with the continuous electronic background. These findings not only serve as fingerprints for verifying the crystal structure of Co3Sn2S2, but also highlight the importance of Raman spectroscopy as an effective tool to study low energy excitations and their interactions in this material.

C-H arylation enables synthesis of imidazole-4-carboxamide (ICA) based fairy chemicals with plant growth-promoting activity

Ayaka Ueda, Kazuma Amaike, Yoko Shirotani, Hideto Ito, Robin Warstat, Jae-Hoon Choi, Hirokazu Kawagishi, Kenichiro Itami

Summary: Imidazole-4-carboxamide (ICA), a type of fairy chemical (FCs) causing fairy ring phenomena, exhibits plant growth inhibitory activity. FCs have the potential to be a new family of plant hormones as they are endogenous in all tested plant species and regulate plant growth. This study focuses on the synthesis of ICA derivatives and evaluation of their activity in rice. Surprisingly, several compounds show unexpected elongation activity in root and shoot growth.

Rapid access to polycyclic thiopyrylium compounds from unfunctionalized aromatics by thia-APEX reaction

Kou P. Kawahara, Hideto Ito, Kenichiro Itami

Summary: We have developed a sulfur-embedding annulative pi-extension (thia-APEX) reaction to efficiently construct a sulfur-embedding cationic hexagonal aromatic ring called thiopyrylium onto unfunctionalized aromatics in a one-step process. The key of the thia-APEX reaction lies in the utilization of S-imidated ortho-arenoyl arenethiols, enabling easy synthesis of diverse pi-extended thiopyryliums. The synthesized thiopyryliums exhibit various absorption and emission properties across the visible light to NIR region, depending on minor structural variations.

,r-Extended Rubrenes via Dearomative Annulative ,r-Extension Reaction

Wataru Matsuoka, Kou P. Kawahara, Hideto Ito, David Sarlah, Kenichiro Itami

Summary: In this study, we successfully achieved a late-stage pi-extension of rubrene using dearomative annulative pi-extension (DAPEX), leading to the generation of rubrene derivatives with an extended aromatic core. These pi-extended rubrenes displayed a marked red shift in absorption and emission spectra, indicating the extension of the rubrene's aromatic pi-system both structurally and electronically. Furthermore, organic field-effect transistor devices using two-side pi-extended rubrene were fabricated, demonstrating the potential utility of these compounds in organic electronics with a comparable carrier mobility to rubrene thin-film transistors.

Synthesis and Properties of Methylene-Bridged [6]Cyclo-2,6-naphthylene

Nobushige Kai, Hideya Kono, Akiko Yagi, Kenichiro Itami

Summary: A novel structurally constrained nanobelt, methylene bridged [6]cyclo-2,6-naphthylene ([6]MCN), was synthesized via the nickel-mediated intramolecular aryl-aryl coupling of a triflated prism[6]arene. The structural and electronic properties of [6]MCN were characterized using NMR studies and photophysical measurements. In contrast to methylene-bridged [6]cycloparaphenylene, our previously synthesized benzene-based analogue, [6]MCN exhibited low strain energy (77.4 kcalmiddotmol(-1)) and bright fluorescence (Phi = 0.20).

Eiki Tomita, Masahiro Kojima, Yuki Nagashima, Ken Tanaka, Haruki Sugiyama, Yasutomo Segawa, Atsushi Furukawa, Katsumi Maenaka, Satoshi Maeda, Tatsuhiko Yoshino, Shigeki Matsunaga

Summary: The synthesis, characterization, and catalytic performance of an iridium(III) catalyst with an electron-deficient cyclopentadienyl ligand were reported. The catalyst was synthesized by complexation of a precursor of the electron-deficient ligand with an iridium compound, followed by oxidation, desilylation and removal of another ligand. The electron-deficient catalyst enabled C-H amidation reactions assisted by a weakly coordinating directing group.

Hideya Kono, Yuanming Li, Guglielmo Monaco, Riccardo Zanasi, Francesco F. Summa, Lawrence T. Scott, Akiko Yagi, Kenichiro Itami

Summary: Cycloparaphenylenes (CPPs) and carbon nanobelts (CNBs) are cyclic molecular nanocarbons with unique properties derived from rigid, strained, and cyclic p-conjugated systems. The synthesis of various sizes of CPPs and CNBs has allowed for the investigation of their size-dependent properties and use in various applications. The synthesis, size-dependent properties, and paratropic belt currents of methylene-bridged [n]cycloparaphenylenes ([n]MCPP, n = 6, 8, 10) were reported and studied.

Adamantane Annulation to Arenes: A Strategy for Property Modulation of Aromatic π-Systems

Takaku Yoshihara, Hiroki Shudo, Akiko Yagi, Kenichiro Itami

Summary: Peripheral structural modifications of arenes have a significant impact on their optoelectronic properties, molecular assembly, and stability. Annulation with an adamantane scaffold is a simple yet powerful modification strategy that leads to unique effects, such as high solubility and enhanced conjugation. The oxidation of adamantane-annulated perylenes produces cationic species with extended emission in the near-infrared region, potentially contributing to the development of groundbreaking pi-materials and novel nanocarbon materials.

Hisayasu Ishibashi, Manuel Rondelli, Hiroki Shudo, Takehisa Maekawa, Hideto Ito, Kiichi Mizukami, Nobuo Kimizuka, Akiko Yagi, Kenichiro Itami

Summary: The active metal template (AMT) strategy is a powerful tool for the synthesis of mechanically interlocked molecules (MIMs) such as rotaxanes and catenanes. In this study, a catenane consisting of [9]CPP and a 2,2'-bipyridine macrocycle was successfully synthesized using the AMT strategy. The catenane's synthetic scaffold allows for diverse and concise post-modification, as demonstrated by catalytic C-H borylation/cross-coupling and metal complexation reactions. Structural and photophysical properties of the synthesized catenane were also analyzed.

Kou P. Kawahara, Hideto Ito, Kenichiro Itami

Summary: This paper describes the synthesis of pi-extended thianthrene derivatives from unfunctionalized aromatics using thia-APEX reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Reductive cyclodimerization of chalcones: exploring the self-adaptability of galvanostatic electrosynthesis

Mauro Garbini, Andrea Brunetti, Riccardo Pedrazzani, Magda Monari, Massimo Marcaccio, Giulio Bertuzzi, Marco Bandini

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
