Koordinative Ringöffnungspolymerisation von Limonencarbamat zur Phosgen‐ und Isocyanatfreien Polyurethan‐Synthese

Angewandte Chemie, EarlyView.
In dieser Studie wird ein phosgen‐ und isocyanatfreier Ansatz zur Herstellung von Polyurethanen unter Verwendung von (R)‐Limonen als biobasiertem Rohstoff vorgestellt. Durch Ringöffnungspolymerisation (ROP) wird Limonencarbamat (LU) mit hoher Effizienz in Polyurethan (PLU) umgesetzt.

A Metal-Free Synthesis of N-Aryl Carbamates under Ambient Conditions.

Angewandte Chemie, 2015
The first chemo- and site-selective process for the formation of N-aryl-carbamates from cyclic organic carbonates and aromatic amines is reported. The reactions proceed smoothly under extremely mild reaction conditions using TBD (triazabicyclodecene) as ...

Cyclization reaction of amines with dialkyl carbonates to yield 1,3-oxazinan-2-ones [PDF]

, 2012
A number of six-membered cyclic carbamates (oxazinanones) were synthesized from the reaction of a primary amine or hydrazine with a dicarbonate derivative of 1,3-diols in a one-pot reaction, in good yield, short time span, and in the absence of a solvent.

Multiple-Insecticide Resistance in Anopheles gambiae Mosquitoes, Southern Côte d’Ivoire

Emerging Infectious Diseases, 2012
Malaria control depends on mosquito susceptibility to insecticides. We tested Anopheles gambiae mosquitoes from Côte d’Ivoire for resistance and screened a subset for target site mutations.

Synthesis of Sulfoximine Carbamates by Rhodium-Catalyzed Nitrene Transfer of Carbamates to Sulfoxides.

Journal of Organic Chemistry, 2015
Sulfoximines are of considerable interest for incorporation into medicinal compounds. A convenient synthesis of N-protected sulfoximines is achieved, under mild conditions, by rhodium-catalyzed transfer of carbamates to sulfoxides.
