A diazido mannose analog as a chemoenzymatic synthon for synthesizing di‐N‐acetyllegionaminic acid‐containing glycosides

19.01.2018 | Abhishek Santra, An Xiao, Hai Yu, Wanqing Li, Yanhong Li, Linh Ngo, John B. McArthur, Xi Chen, Angewandte Chemie International Edition, 2018

A novel strategy is developed to expand the scope of chemoenzymatic synthetic products by designing a chemoenzymatic synthon. The synthon is enzymatically converted to carbohydrate analogs which are readily derivatized chemically to produce desired targets. The strategy is demonstrated for ...

Tuning High‐Temperature Wetting Behavior of Metal toward Ultrafine Nanoparticles

18.01.2018 | Yubing Zhou, Bharath Natarajan, Yanchen Fan, Hua Xie, Chunpeng Yang, Shaomao Xu, Yonggang Yao, Feng Jiang, Qianfan Z ..., Angewandte Chemie International Edition, 2018

The interaction between the metal nanoparticles and their substrate plays a critical role in determining the particle morphology, distribution, and properties. Here we present the pronounced impact of a thin oxide coating to the dispersion of metal nanoparticles on a carbon matrix. We employ ...

Targeting a dark excited state of HIV‐1 nucleocapsid by anti‐retroviral thioesters revealed by NMR

18.01.2018 | Lalit Deshmukh, Vitali Tugarinov, Daniel H. Appella, G. Marius Clore, Angewandte Chemie International Edition, 2018

HIV‐1 nucleocapsid (NCp7) is a two Cys2HisCys zinc knuckle (N‐Zn and C‐Zn) protein that plays a key role in viral replication. Here we characterize NCp7 conformational dynamics by NMR relaxation dispersion and chemical exchange saturation transfer measurements. While the N‐Zn knuckle is ...

Elucidation of the Oxygen Reduction Volcano in Alkaline Media using a Copper‐Platinum(111) Alloy

18.01.2018 | Kim Degn Jensen, Jakub Tymoczko, Jan Rossmeisl, Aliaksandr Bandarenka, Ib Chorkendorff, Maria Escudero-Escribano, I ..., Angewandte Chemie International Edition, 2018

Herein we experimentally explore the relationship between the binding of the reaction intermediates and oxygen reduction activity in alkaline media. By introducing Cu into the 2nd surface layer of a Pt(111) single crystal, we tune the surface reactivity. We demonstrate that in both NaOH and KOH, ...

Oxidative mechanochemistry for direct, room‐temperature, solvent‐free conversion of palladium and gold metals into soluble salts and coordination complexes

18.01.2018 | Jean-Louis Do, Davin Tan, Tomislav Friscic, Angewandte Chemie International Edition, 2018

Noble metals are valued critical elements whose chemical activation or recycling is challenging, traditionally requiring high temperatures, strong acids or bases, or aggressive complexation agents. Using elementary palladium and gold, we demonstrate mechanochemistry for noble metal activation ...

Stable and Highly Efficient Electrochemical Production of Formic Acid from Carbon Dioxide Using Diamond Electrodes

18.01.2018 | Keisuke Natsui, Hitomi Iwakawa, Norihito Ikemiya, Kazuya Nakata, Yasuaki Einaga, Angewandte Chemie International Edition, 2018

High faradaic efficiencies can be achieved in the production of formic acid (HCOOH) by metal electrodes, such as Sn or Pb, in the electrochemical reduction of carbon dioxide (CO2). However, the stability and environmental load in using them are problematic. Here, we investigated the ...

MoP Nanoparticles Supported on In‐doped Porous Carbon: Outstanding Catalysts for High‐efficient CO2 Electroreduction

18.01.2018 | Xiaofu Sun, Lu Lu, qinggong Zhu, Congyi Wu, Dexin Yang, Chunjun Chen, Buxing Han, Angewandte Chemie International Edition, 2018

Electrochemical reduction of CO2 into value‐added product is an interesting area. In this work, we synthesized MoP nanoparticles supported on porous carbon using metal‐organic frameworks as the carbon precusor, and conducted the first work on CO2 electroreduction using MoP‐based catalyst. It was ...

Peripheral Templation‐Modulated Interconversion between an A4L6 Tetrahedral Anion Cage and A2L3 Triple Helicate with Guest Capture/Release

18.01.2018 | Xuemin Bai, Chuandong Jia, Yanxia Zhao, Dong Yang, Shi‐Cheng Wang, Anyang Li, Yi‐Tsu Chan, Yao‐Yu Wang, Xiao‐Juan Ya ..., Angewandte Chemie International Edition, 2018

Peripheral templation was used to stabilize an unusual A4L6 tetrahedral cage (A=anion, L=ligand) as reported by C. Jia, B. Wu et al. in their Communication (DOI: 10.1002/anie.201712080). The A4L6 cage can be transformed into an A2L3 helicate in response to different stimuli (change template, ...

Photoinduced Pedalo‐Type Motion in an Azodicarboxamide‐Based Molecular Switch

18.01.2018 | Saeed Amirjalayer, Alberto Martinez‐Cuezva, Jose Berna, Sander Woutersen, Wybren Jan Buma, Angewandte Chemie International Edition, 2018

A new class of light‐controlled molecular switches based on an azodicarboxamide chromophore is described by S. Amirjalayer, S. Woutersen, W. J. Buma et al. in their Communication (DOI: 10.1002/anie.201709666). These switches work like the crankshaft of a bicycle and, as switching requires a ...

Ion Specificity on Electric Energy Generated by Flowing Water Droplets

18.01.2018 | Junwoo Park, Suhwan Song, ChaeHo Shin, YoungJun Yang, Stefan A. L. Weber, Eunji Sim, Youn Sang Kim, Angewandte Chemie International Edition, 2018

Abstract The development of energy‐conversion devices using water movement has actively progressed. Ionovoltaic devices, which are driven by ion dynamics, show ion specificity by which different ions with identical charges show different output performance. However, the ion specificity remains ...
