starting from a wide range of 2-fluoroaromatic acids or esters bearing further aryl fluorine, trifluoromethyl, and cyano substituents

Palladium catalyzed direct arylation of azine N-oxides using aryl triflates to afford the corresponding 2-aryl azine N-oxides is described. The reaction is carried out with a range of both N-oxides and aryl triflates. The arylation can be carried out in sequence to yiel...

The relative antibacterial activities of penicillins and cephalosporins are discussed in terms of their differing abilities to complex to and react with penicillin-binding proteins. The insights gained from such an analysis are being used to attempt the design of new ki...

An asymmetric formal synthesis of fasicularin (1) is described. This natural product, isolated from the extracts of the marine invertebrate Nephteis fasicularis, has shown modest cytotoxicity towards Vero cells. Fasicularin is among only two members of the cylindricine ...

Abstract A new quinoline-2-carboxylic acid, 4-hydroxy-6-methoxyquinoline-2-carboxylic acid (6-methoxy-kynurenic acid), has been isolated from Ephedra pachyclada ssp. sinaica . Kynurenic and 6-hydroxykynurenic acids, previously reported from plants, were also isolated fr...

A novel regioselective rhodium(I)-catalyzed hydroarylation of unactivated alkenes with arylboronic acids is described. The catalytic system employs [Rh(COD)OH]2 and BINAP to effect the addition of ...

2-Azametallacyclobutanes have been reported for a number of metals. This Perspective provides a brief overview of 2-azametallacyclobutanes, focusing on complexes in which the ring nitrogen is anionic (amido).

Protocol simplification is an important aspect in the development of organic reactions such as heteroarene functionalizations. An operationally facile protocol for the direct C–H alkylation of heteroarenes with unactivated ethers has been developed. The Minisci-type rad...

Lewis acid catalyzed reaction of 2-furaldehyde and secondary amines results in the formation of 4,5-diaminocyclopent-2-enones exclusively as the trans diastereomers: computational studies support the stereochemistry of the adducts as arising from a thermal conrotatory π...

The electronic and geometrical structures of chlorine-substituted sulfur fluorides SF n Cl (n=1-5) as well as their singly charged negative anions have been studied by a computational method based on density functional theory. It was found that the stability of neutral ...
