A new polymer-attached reagent for the oxidation of primary and secondary alcohols.

Organic letters

Sourkouni-Argirusi G, Kirschning A.
PMID: 11101418
Org Lett. 2000 Nov 30;2(24):3781-4. doi: 10.1021/ol006483t.

A new, polymer-bound reagent system for the efficient oxidation of primary alcohols to aldehydes and secondary alcohols to ketones in the presence of a catalytic amount of 2,2,6, 6-tetramethyl-1-piperidinyloxyl (TEMPO) is described. In most cases, workup of this heavy...

The influence of microgravity on the morphology of identified cerebral neurons in a cricket (Acheta domesticus).

Journal of gravitational physiology : a journal of the International Society for Gravitational Physiology

Kirschnik U, Horn E, Agricola HJ.
PMID: 14703671
J Gravit Physiol. 2002 Jul;9(1):P27-8.

Studies in cricket larvae (Acheta domesticus) revealed that descending sulfakinin-ir-neurons (PDS-neurons) from the sensorimotor area of the brain are insensitive to gravity deprivation if they were exposed to microgravity after determination of their shape. In the project CRISP-2, we...

Hetero-Diels-Alder reactions of cyclic ketone derived enamide. A new and efficient concept for the asymmetric Robinson annulation.

Organic letters

Gallier F, Hussain H, Martel A, Kirschning A, Dujardin G.
PMID: 19537770
Org Lett. 2009 Jul 16;11(14):3060-3. doi: 10.1021/ol901065e.

Chiral enamides, easily prepared in one step from a cyclic ketone and an oxazolidinone, are successfully employed in high-yielding, endo, and facially selective Hetero-Diels-Alder reactions involving activated oxadienes and Siever's reagent as catalyst. From the resulting bicyclic heteroadducts, a...

Towards a biocompatible artificial lung: Covalent functionalization of poly(4-methylpent-1-ene) (TPX) with cRGD pentapeptide.

Beilstein journal of organic chemistry

Möller L, Hess C, Paleček J, Su Y, Haverich A, Kirschning A, Dräger G.
PMID: 23504394
Beilstein J Org Chem. 2013;9:270-7. doi: 10.3762/bjoc.9.33. Epub 2013 Feb 08.

Covalent multistep coating of poly(methylpentene), the membrane material in lung ventilators, by using a copper-free "click" approach with a modified cyclic RGD peptide, leads to a highly biocompatible poly(methylpentene) surface. The resulting modified membrane preserves the required excellent gas-flow...
