Efficient Syntheses of Diverse N-Heterocycles: The Molybdenum(VI)-Catalyzed Reductive Cyclization of Nitroarenes using Pinacol as a Deoxygenating­ Agent

open access: yesSynOpen, 2018
Molybdenum(VI)-catalyzed domino reductive cyclization of nitroarenes has been devised for the syntheses of 1,4-benzoxazines and 1,4-benzothiazines in the presence of pinacol as deoxygenating agent.

Evaluation of Hemoadsorption Capacity of the CytoSorb Adsorber for Toxic Doses of Diclofenac and Meloxicam in Porcine Plasma

open access: yesJournal of Clinical Apheresis, Volume 41, Issue 3, June 2026.
ABSTRACT The objective of this in vitro experimental was to determine the utility of hemoadsorption (HA) using the CytoSorb adsorber to remove meloxicam and diclofenac from porcine plasma. For this purpose 12 1‐L aliquots of porcine plasma, 6 units were spiked with 293 μg/mL (262–320 μg/mL) diclofenac and 6 with 42.8 μg/mL (41.4–44.7 μg/mL) meloxicam ...

Benzothiazines in Synthesis. A Total Synthesis of Pseudopteroxazole. [PDF]

open access: yesChemInform, 2005
An enantioselective total synthesis of the naturally occurring antitubercular agent pseudopteroxazole is described. The synthesis is organized around the use of a stereoselective, intramolecular addition of a sulfoximine carbanion to an alpha,beta-unsaturated ester to form an enantiomerically pure benzothiazine.
