Sulfoximines and sulfonimidamides are promising compounds for medicinal and agrochemistry. As monoaza analogues of sulfones and sulfonamides, respectively, they combine good physicochemical properties, high stability, and the ability to build complexity from a three-dimensional core. However, a lack of quick and efficient methods to prepare these compounds has hindered their uptake in molecule discovery programmes. Herein, we describe a unified, one-pot approach to both sulfoximines and sulfonimidamides, which exploits the high electrophilicity of sulfinyl nitrenes. We generate these rare reactive intermediates from a novel sulfinylhydroxylamine (R-O-N=S=O) reagent through an N-O bond fragmentation process. Combining sulfinyl nitrenes with carbon and nitrogen nucleophiles enables the synthesis of sulfoximines and sulfonimidamides in a reaction time of just 15 min. Alkyl, (hetero)aryl, and alkenyl organometallic reagents can all be used as the first or second component in the reaction, while primary and secondary amines, and anilines, all react with high efficiency as the second nucleophile. The tolerance of the reaction to steric and electronic factors has allowed for the synthesis of the most diverse set of sulfoximines and sulfonimidamides yet described. Experimental and computational investigations support the intermediacy of sulfinyl nitrenes, with nitrene formation proceeding via a transient triplet intermediate before reaching a planar singlet species.

Several 9-chloro-11H-indeno[1,2-c]quinolin-11-one derivatives have been designed which is replacing side chains with different groups containing oxygen, nitrogen or sulfur atoms. Substitution of C-6 on the starting structure, 6,9-dichloro-11H-indeno[1,2-c]quinolin-11-one, using apposite nucleophilic group with a suitable base or acid could be obtained 28 novel tetracyclic azafluorenone derivatives. The cytotoxic activity of these analogues was examined in cancer cell lines by MTT assay and compounds 4, 5, 13, and 26 were selected to evaluate in topoisomerase I drug screening assay, respectively. At the same time, 17 compounds were selected for NCI-60 anticancer drug screen to prevent the narrower concept of an in vitro screening model. Its worth to find that 9-chloro-6-(piperazin-1-yl)-11H-indeno[1,2-c]quinolin-11-one (12) showed greater cytotoxicity than another azafluorenone derivatives with an average GI(50) of 10.498 mu M over 60 cell lines. We also found that another analogue, 9-chloro-6-(2-methylpiperazin-1-yl)-11H-indeno[1,2-c]quinolin-11-one (13), exhibited preferential growth inhibition effect toward cancer cell lines and showed a significant inhibitory effect on topoisomerase I.

Metal-catalyzed cross-coupling reactions are among the most important transformations in organic synthesis. However, the use of C-H activation for sp(2) C-N bond formation remains one of the major challenges in the field of cross-coupling chemistry. Described herein is the first example of the synergistic combination of copper catalysis and electrocatalysis for aryl C-H amination under mild reaction conditions in an atom-and step-economical manner with the liberation of H-2 as the sole and benign byproduct.

A new method for the direct and stereoselective synthesis of 3-substituted isoindolinones via Rh(iii)-catalyzed chiral N-sulfinyl amide directed asymmetric [4 + 1] annulation of benzamides with acrylic esters has been developed. The reaction proceeded through an oxidative C-H olefination and a subsequent cyclization by intramolecular aza-Michael addition, producing a series of diastereoisomeric chiral isoindolinones (20 examples) in generally good yields with a dr value up to 5.5 : 1. The absolute configurations of the newly formed C-stereocenters in the major and minor diastereomers of the catalysis product have been determined by X-ray crystal diffraction analysis to be S and R, respectively. The separation of the major diastereoisomers from the catalysis products and subsequent removal of the N-sulfinyl chiral auxiliary afforded enantiomerically pure (S)-isoindolinones. The application of the obtained (S)-isoindolinones in the synthesis of several biologically active isoindolinones such as (S)-PD172938, (S)-pazinaclone and (S)-pagoclone is presented.

We report a highly chemoselective palladium-catalyzed Catellani-type amination of aryl iodides terminated by the Heck reaction using allylic esters as terminating reagents. 2-Aminocinnamyl esters were formed exclusively via beta-H elimination rather than beta-OAc elimination without the assistance of a silver salt. This protocol represents a useful extension of Catellani-type transformations.

Novel fluorinated 2-substituted 1,3-benzothiazin-4-ones were obtained through the addition of N-nucleophiles to ortho-fluorobenzoylisothiocyanates, followed by cyclization of fluorobenzoyl-thioureas. Synthetic approaches to original 2-cycloalkylimino- and 2-carbonylpiperazino- substituted benzothiazinones, bearing different number of fluorine atoms in the benzene ring have been found. 2-Ethoxycarbonylpiperazino-5-fluoro-1,3-benzothiazin-4-one proved to exhibit a high tuberculostatic activity in vitro (MIC 0.7 microgram/mL), thus indicating that a search of biologically active compounds in this family of heterocycles appears to be a reasonable approach.
