(Z)-4-n-Butyl-2-(4-chlorobenzylidene)-2H-1,4-benzothiazin-3(4H)-one

IUCrData, 2017
In the title compound, C19H18ClNOS, the thiazin-3-one ring adopts a slightly distorted screw-boat conformation. An intramolecular C—H...S hydrogen bond encloses an S(6) ring and affects the overall conformation of the molecule. The dihedral angle between

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

Journal 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 ...

Synthesis of Furanone Fused 1,2-Benzothiazine by Rh(III)-Catalyzed C-H Activation: Regioselective Oxidative-Annulation leading to in situ Lactonization in One-Pot.

Journal of Organic Chemistry, 2019
Sulfoximine directed C-H activation strategy catalyzed by Rh-catalyst leads to an efficient synthesis of furanone fused 1,2-benzothiazine. In this reaction, cascade C-H activation, regioselective annulations, and lactonization, occur in one-pot.

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

ChemInform, 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.

Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.

Design of Intrinsically Stable Hole‐Selective Self‐Assembled Monolayers by Introducing Fused‐Ring Intramolecular Donor–Acceptor Interactions

Angewandte Chemie, Volume 137, Issue 28, July 7, 2025.
Herein, we develop a novel SAM molecular design strategy by introducing fused‐ring intramolecular donor–acceptor (D–A) interactions. The designed molecule, JJ32, features a benzo[5,6][1,4]thiazino[2,3‐b]quinoxaline skeleton, where strong D–A interactions enhance charge delocalization and downshift the LUMO energy level.

Proteome‐Wide Analysis of Cysteine S‐Sulfenylation Using a Benzothiazine‐Based Probe

Current Protocols in Protein Science, 2018
Oxidation of a protein cysteinyl thiol (Cys‐SH) to S‐sulfenic acid (Cys‐SOH) by a reactive oxygen species (e.g., hydrogen peroxide), which is termed protein S‐sulfenylation, is a reversible post‐translational modification that plays a crucial role in ...
