Intermolecular Cross-Acyloin Reactions by Fluoride-Promoted Additions of O-Silyl Thiazolium Carbinols.

Synlett : accounts and rapid communications in synthetic organic chemistry

Mathies AK, Mattson AE, Scheidt KA.
PMID: 21132061
Synlett. 2009 Jan 01;2009(3):377-383. doi: 10.1055/s-0028-1087555.

The addition of acyl anion equivalents to aliphatic aldehydes (crossed-acyloin reaction) has been developed. Cesium fluoride with isopropanol as solvent promotes the addition of O-silyl thiazolium carbinols to various aliphatic aldehydes in moderate to good yields. These reactions represent...

First experiment on fission transients in highly fissile spherical nuclei produced by fragmentation of radioactive beams.

Physical review letters

Schmitt C, Nadtochy PN, Heinz A, Jurado B, Kelić A, Schmidt KH.
PMID: 17678357
Phys Rev Lett. 2007 Jul 27;99(4):042701. doi: 10.1103/PhysRevLett.99.042701. Epub 2007 Jul 25.

We report on a novel experimental approach for studying the dissipative spreading of collective motion in a metastable nuclear system, using, for the first time, highly fissile nuclei with spherical shape. This was achieved by fragmentation of 45 radioactive...

Lewis base-catalyzed additions of alkynes using trialkoxysilylalkynes.

Organic letters

Lettan Ii RB, Scheidt KA.
PMID: 16018627
Org Lett. 2005 Jul 21;7(15):3227-30. doi: 10.1021/ol051030f.

[reaction: see text]. The Lewis base-catalyzed additions of alkynyl nucleophiles to aldehydes, ketones, and imines is described. Mechanistic studies strongly indicate that the use of new triethoxysilylalkynes facilitates access of a reactive hypervalent silicate intermediate. This activated carbon nucleophile...

N-heterocyclic carbene-catalyzed rearrangements of vinyl sulfones.

Chemical science

Atienza RL, Roth HS, Scheidt KA.
PMID: 22448316
Chem Sci. 2011;2(9):1772-1776. doi: 10.1039/C1SC00194A. Epub 2011 Jun 10.

N-heterocyclic carbenes catalyze the rearrangement of 1,1-bis(arylsulfonyl)ethylene to the corresponding trans-1,2-bis(phenylsulfonyl) under mild conditions. Tandem rearrangement/cycloadditions have been developed to capitalize on this new process and generate highly substituted isoxazolines and additional heterocyclic compounds. Preliminary mechanistic studies support a...

Asymmetric Methods for the Synthesis of Flavanones, Chromanones, and Azaflavanones.

European journal of organic chemistry

Nibbs AE, Scheidt KA.
PMID: 22876166
European J Org Chem. 2012 Jan;2012(3):449-462. doi: 10.1002/ejoc.201101228. Epub 2011 Dec 09.

Flavanones, chromanones, and related structures are privileged natural products that display a wide variety of biological activities. Although flavanoids are abundant in nature, there are a limited number of available general and efficient synthetic methods for accessing molecules of...

Appropriate Sequence for Afatinib and Cisplatin Combination Improves Anticancer Activity in Head and Neck Squamous Cell Carcinoma.

Frontiers in oncology

Front Oncol. 2018 Oct 05;8:432. doi: 10.3389/fonc.2018.00432. eCollection 2018.

Despite a better understanding in head and neck tumors pathogenesis as well as improvements in radiotherapy and surgery, locally advanced head and neck squamous cell carcinoma (HNSCC) remains of poor prognosis. One promising target is the epidermal growth factor...

Combining community resurvey data to advance global change research.

Bioscience. 2016 Dec 21;67(1):73-83. doi: 10.1093/biosci/biw150.

More and more ecologists have started to resurvey communities sampled in earlier decades to determine long-term shifts in community composition and infer the likely drivers of the ecological changes observed. However, to assess the relative importance of, and interactions...

In-process measuring of the electrical shunt resistance of laser-scribed thin-film stacks by nested circular scribes.

The Review of scientific instruments

Wang X, Ehrhardt M, Lorenz P, Scheit C, Ragnow S, Ni XW, Zimmer K.
