Synthesis of Trifluoromethylated Dithiocarbamates via Photocatalyzed Substitution Reaction: Pentafluoropyridine as Activating Reagent

Published: 22 January 2021

Author(s): Artem A. Zemtsov, Sergey S. Lunkov, Vitalij V. Levin, Alexander D. Dilman

Abstract A method for the synthesis of trifluoromethyl‐substituted dithiocarbamates from aldehydes is described. The reaction involves nucleophilic trifluoromethylation, derivatization of the silyloxy‐group with pentafluoropyridine, and substitution of the fluorinated pyridinyloxy group by dithiocarbamate anion. The substitution step is performed in the presence of 12‐phenyl‐12H‐benzo[b]phenothiazine and copper cyanide under irradiation of 400 nm LED.

Oxidative Transformation of Biomass into Formic Acid

Published: 22 January 2021

Author(s): Prakash Kumar Sahoo, Tong Zhang, Shoubhik Das

Abstract Formic acid (FA) is well‐known as a promising hydrogen source as well as a valuable chemical for the industries of textiles, pharmaceuticals etc. In fact, 1.137 million metric tons of FA is required worldwide per year to meet the current demand. Therefore, there is a strong interest for the generation of FA in a sustainable way to meet the future demand. Inspired by this information, several strategies have been considered for the sustainable synthesis of FA. Herein, we summarise the...

Stimuli‐Responsive Self‐Sorting Hybrid Hydrogen‐Bonded/Metal‐Coordinated Cage

Published: 22 January 2021

Author(s): Petr Motloch, Christopher A. Hunter

Abstract The self‐assembly of a unique molecular container is reported: a hybrid hydrogen‐bonded/metal‐coordinated cage where both hydrogen‐bonding and metal‐coordination form the crucial part of the topology. The hybrid cage was prepared combining hydrogen‐bonded rosette motif and palladium(II)/platinum(II) coordination to a pyridine ligand. It was also shown that the hybrid cage could be prepared by integrative self‐sorting from simple components. For the first time the genuine dual...

Novel, Chiral, and Enantiopure C2‐Symmetric Thioureas Promote Asymmetric Protio‐Pictet‐Spengler Reactions by Anion‐Binding Catalysis

Published: 22 January 2021

Author(s): Michele Retini, Francesca Bartoccini, Giovanni Zappia, Giovanni Piersanti

Abstract Although anion‐binding processes are well‐known for their crucial role in molecular recognition, they have only recently been utilized for catalysis. Herein, a new class of chiral, enantiopure C2‐symmetrical thioureas that, in combination with 4‐methoxybenzoic acid, promotes the enantioselective protio‐Pictet‐Spengler reaction to provide unprotected tetrahydro‐β‐carbolines in good yields (40–93 %) and moderate‐to‐high enantioselectivities (34–95 % ee) in one step from tryptamine and...

Forty Years after the Discovery of Its Nucleolytic Activity: [Cu(phen)2]2+ Shows Unattended DNA Cleavage Activity upon Fluorination

Published: 22 January 2021

Author(s): Carsten Lüdtke, Sebastian Sobottka, Julian Heinrich, Phil Liebing, Stefanie Wedepohl, Biprajit Sarkar, Nora Kulak

Abstract [Cu(phen)2]2+ (phen=1,10‐phenanthroline) is the first and still one of the most efficient artificial nucleases. In general, when the phen ligand is modified, the nucleolytic activity of its CuII complex is significantly reduced. This is most likely due to higher steric bulk of such ligands and thus lower affinity to DNA. CuII complexes with phen ligands having fluorinated substituents (F, CF3, SF5, SCF3) surprisingly showed excellent DNA cleavage activity—in contrast to the...

Synthesis and Determination of Absolute Configuration of Zealexin A1, a Sesquiterpenoid Phytoalexin from Zea mays

Published: 22 January 2021

Author(s): Arata Yajima, Mikaho Shimura, Tatsuo Saito, Ryo Katsuta, Ken Ishigami, Alisa Huffaker, Eric A. Schmelz

Abstract The enantioselective synthesis of zealexin A1, a sesquiterpene phytoalexin isolated from maize Zea mays is described for the first time. Our methodology for the total synthesis of zealexin A1 involved the stereoselective construction of the stereogenic center via enzymatic resolution followed by Johnson–Claisen rearrangement. The absolute configuration of the natural product was determined through gas chromatography analyses for the methyl esters for both synthetic and natural...

Rhodium‐Catalyzed Chemodivergent Regio‐ and Enantioselective Allylic Alkylation of Indoles

Published: 22 January 2021

Author(s): Minghe Sun, Min Liu, Changkun Li

Abstract The control of C3/N1 chemoselectivity in indole alkylation with the same electrophiles is still challenging. An Rh/bisoxazolinephosphane‐catalyzed chemodivergent regio‐ and enantioselective allylic alkylation of indoles was developed. Chiral C3‐ and N1‐allylindoles can be selectively obtained with high branched/linear ratio and up to 99 % ee by changing the counteranion of Rh, the allylic carbonate, the reaction temperature, and the ligand.

Zinc Oxide Defect Microstructure and Surface Chemistry Derived from Oxidation of Metallic Zinc: Thin‐Film Transistor and Sensor Behavior of ZnO Films and Rods

Published: 22 January 2021

Author(s): Rudolf C. Hoffmann, Shawn Sanctis, Maciej O. Liedke, Maik Butterling, Andreas Wagner, Christian Njel, Jörg J. Schneider

Abstract Zinc oxide thin films are fabricated by controlled oxidation of sputtered zinc metal films on a hotplate in air at temperatures between 250 and 450 °C. The nanocrystalline films possess high relative densities and show preferential growth in (100) orientation. Integration in thin‐film transistors reveals moderate charge carrier mobilities as high as 0.2 cm2 V−1s−1. The semiconducting properties depend on the calcination temperature, whereby the best performance is achieved at 450 °C....

Author(s): Jay Prakash Soni, Swanand Vinayak Joshi, Krishna Sowjanya Chemitikanti, Nagula Shankaraiah

Abstract The application of microwave technique in chemical laboratory rooted back in 1986 and found advantageous over conventional approaches. On the other side, poly‐aza‐heterocycles are influencing organic frameworks with a fascinating chemistry and well explored by employing microwave‐assisted organic reactions. In the present review, we have thoroughly updated rousing literatures of microwave‐assisted synthesis and reactions of various poly‐aza‐heterocycles viz., triazole, tetrazole,...
