Nucleophilic borylation of fluorobenzenes with reduced arylboranes.

Chemical communications (Cambridge, England)

Budy H, Prey SE, Buch CD, Bolte M, Lerner HW, Wagner M.
PMID: 34881754
Chem Commun (Camb). 2021 Dec 23;58(2):254-257. doi: 10.1039/d1cc06225e.

Two challenging but rewarding topics in chemical synthesis are C-F-bond activation and the development of B-centered nucleophiles. We have now tackled both subjects simultaneously by forming aryl-B bonds

Flow visualization and force measurement of the clapping effect in bio-inspired flying robots.

Balta M, Deb D, Taha HE.
PMID: 34584023
Bioinspir Biomim. 2021 Oct 26;16(6). doi: 10.1088/1748-3190/ac2b00.

In this paper, we perform experimental investigations of the aerodynamic characteristics due to wing clapping in bio-inspired flying robots; i.e., micro-air-vehicles (MAVs) that fly by flapping their wings. For this purpose, four flapping MAV models with different levels of...

BACKGROUND: Federal regulations stipulate that behavioral interventions be used for behavioral and psychological symptoms of distress in dementia (BPSD). Care community staff have difficulty implementing these approaches.PURPOSE: This study tested an implementation strategy, the Evidence Integration Triangle for BPSD...

We report on a search for nuclear recoil signals from solar ^{8}B neutrinos elastically scattering off xenon nuclei in XENON1T data, lowering the energy threshold from 2.6 to 1.6  keV. We develop a variety of novel techniques to limit...

An inorganic propellane with central B-B bond.

9,10-Dihydroanthracene-9,10-diyl-bridged B(2)(NMe(2))(2) readily adds [H(2)NMe(2)](+), HCl and F(3)CCOOH across its partial B=N double bond(s), thereby forming mono- or diadducts; treatment with 1-iso-propyl-2-mercaptoimidazole leads to a triply B-B-bridged propellane-like structure.

Synthesis of bromo-, boryl-, and stannyl-functionalized 1,2-bis(trimethylsilyl)benzenes via Diels-Alder or C-H activation reactions.

J Org Chem. 2012 Apr 06;77(7):3518-23. doi: 10.1021/jo3002936. Epub 2012 Mar 28.

1,2-Bis(trimethylsilyl)benzenes are key starting materials for the synthesis of benzyne precursors, Lewis acid catalysts, and certain luminophores. We have developed efficient, high-yield routes to functionalized 4-R-1,2-bis(trimethylsilyl)benzenes, starting from either 1,2-bis(trimethylsilyl)acetylene/5-bromopyran-2-one (2) or 1,2-bis(trimethylsilyl)benzene (1)/bis(pinacolato)diborane. In the first reaction, 5...

A DAP5/eIF3d alternate mRNA translation mechanism promotes differentiation and immune suppression by human regulatory T cells.

Nature communications

Volta V, Pérez-Baos S, de la Parra C, Katsara O, Ernlund A, Dornbaum S, Schneider RJ.

Nat Commun. 2021 Nov 30;12(1):6979. doi: 10.1038/s41467-021-27087-w.

Regulatory T cells (Treg cells) inhibit effector T cells and maintain immune system homeostasis. Treg cell maturation in peripheral sites requires inhibition of protein kinase mTORC1 and TGF-beta-1 (TGF-beta). While Treg cell maturation requires protein synthesis, mTORC1 inhibition downregulates...

The serendipitous discovery of ketamine's antidepressant effects represents one of the major landmarks in neuropsychopharmacological research of the last 50 years. Ketamine provides an exciting challenge to traditional concepts of antidepressant drug therapy, producing rapid antidepressant effects seemingly without...
