A single-step continuous flow method has been developed that gives expedited access to complex heterocycles via an intramolecular photochemical cyclization. Herein we report the first examples of the photochemically-induced generation of thieno[3,2-c]quin
Benzoisothiazolone organo/copper-cocatalyzed redox dehydrative construction of amides and peptides from carboxylic acids using (EtO)3P as the reductant and O2 in air as the terminal oxidant

Carboxylic acids and amine/amino acid reactants can be converted to amides and peptides at neutral pH within 5-36 h at 50 °C using catalytic quantities of a redox-active benzoisothiazolone and a copper complex. These catalytic "oxidation-reduction condensation" reactions are carried out open to dry air using O2 as the terminal oxidant and a slight excess of triethyl phosphite as the reductant. Triethyl phosphate is the easily removed byproduct. These simple-to-run catalytic reactions provide practical and economical procedures for the acylative construction of C-N bonds.

A series of nicotinoyl based organoselenium compounds, [2-NC 5H3(3-COOH)Se]2 (1), [2-NC5H 3(3-CO)Se-Se] (2), [2-NC5H3(3-CONH 2)Se]2 (3), [2-NC5H3(3-CONHPh)Se] 2 (4), [2-NC5H3(3-CONHpyrimidine)Se] 2 (5), [2-NC5H3(3-CONHPh)SeBr] (6) and [2-NC5H3(3-CONHPh)SeI] (7) have been synthesized and characterized by absorption, IR, NMR (1H, 13C{ 1H}, 77Se{1H}) and mass spectrometry. The crystal structures of [2-NC5H3(3-CO)Se-Se] (2) and [2-NC5H3(3-CONHPh)Se]2 (4) have been determined. The structure of (4) revealed the existence of two intra-molecular Se?X (X = O and N) interactions, as a result of this, C-Se-Se-C torsion angle is unusually large (180°). The GPx mimicking activity of these compounds has been evaluated using methods based on 1H NMR spectroscopy and HPLC. Free radical scavenging ability of the compounds was examined by DPPH and deoxyribose assay. All these studies indicated that the compound (3) not only showed highest GPx activity but also has a very good free radical scavenging ability thus making it a novel structure for development of nicotine based antioxidants.
