Ligand-enabled ruthenium-catalyzed meta-C−H alkylation of (hetero)aromatic carboxylic acids

Autor: Xianglin Luo, Peichao Hou, Jiayi Shen, Yifeng Kuang, Fengchao Sun, Huanfeng Jiang, Lukas J. Gooßen, Liangbin Huang

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-10 (2024)

Abstract Carboxylates are ideal directing groups because they are widely available, readily cleavable and excellent linchpins for diverse follow-up reactions. However, their use in meta-selective C−H functionalizations remains a substantial unmet c

Taking electrodecarboxylative etherification beyond Hofer–Moest using a radical C–O coupling strategy

Autor: Ángel Manu Martínez, Davit Hayrapetyan, Tim van Lingen, Marco Dyga, Lukas J. Gooßen

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-8 (2020)

Since its discovery, the Hofer-Moest mechanism strongly limits the scope of electrochemical decarboxylative etherification. Here, the authors report the electrochemical conversion of carboxylic acids into alkyl benzotriazole ethers expanding the scop

RotoMate: An open-source, 3D printed autosampler for use with benchtop nuclear magnetic resonance spectrometers

Autor: Marco Dyga, Christoph Oppel, Lukas J. Gooßen

Publikováno v: HardwareX, Vol 10, Iss , Pp e00211- (2021)

Benchtop nuclear magnetic resonance (NMR) spectrometers are versatile analytic instruments with low acquisition and operation cost. However, in the basic version, samples must be manually measured one after the other. We herein describe the open-sour

Synthesis of a tyrosinase inhibitor by consecutive ethenolysis and cross-metathesis of crude cashew nutshell liquid

Autor: Jacqueline Pollini, Valentina Bragoni, Lukas J. Gooßen

Publikováno v: Beilstein Journal of Organic Chemistry, Vol 14, Iss 1, Pp 2737-2744 (2018)

A convenient and sustainable three-step synthesis of the tyrosinase inhibitor 2-hydroxy-6-tridecylbenzoic acid was developed that starts directly from the anacardic acid component of natural cashew nutshell liquid (CNSL). Natural CNSL contains 60–7

Atom-economic catalytic amide synthesis from amines and carboxylic acids activated in situ with acetylenes

Autor: Thilo Krause, Sabrina Baader, Benjamin Erb, Lukas J. Gooßen

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-7 (2016)

Amide formation is a ubiquitous reaction in organic chemistry, but suffers from the problem of generating large amounts of waste. Here, the authors report a catalytic amide synthesis by the ruthenium catalysed addition of carboxylic acids to acetylen

Pd-catalyzed decarboxylative Heck vinylation of 2-nitrobenzoates in the presence of CuF2

Autor: Lukas J. Gooßen, Bettina Zimmermann, Thomas Knauber

Publikováno v: Beilstein Journal of Organic Chemistry, Vol 6, Iss 1, p 43 (2010)

A new protocol for the decarboxylative Heck vinylation of benzoic acids is disclosed. In the presence of a catalyst system generated in situ from Pd(OAc)2 (2 mol %), CuF2 (2 equiv), and benzoquinone (0.5 equiv) in NMP, a wide range of olefins were co
