Identification of organophosphorus simulants for the development of next-generation detection technologies

Organophosphorus (OP) chemical warfare agents (CWAs) represent an ongoing threat but the understandable widespread prohibition of their use places limitations on the development of technologies to counter the effects of any OP CWA release. Herein, we describe new, accessible methods for the identification of appropriate molecular simulants to mimic the hydrogen bond accepting capacity of the PO moiety, common to every member of this class of CWAs. Using the predictive methodologies developed herein, we have identified OP CWA hydrogen bond acceptor simulants for soman and sarin. It is hoped that the effective use of these physical property specific simulants will aid future countermeasure developments.

Late-Stage Aromatic C-H Oxygenation

Synthetic methods for oxidative aromatic C-O bond formation are sparse, despite their demand in metabolite synthesis for drug discovery and development. We report a novel methodology for late-stage C-O bond formation of arenes. The reaction proceeds with excellent functional group tolerance even for highly functionalized substrates. The resulting aryl mesylates provide access to potential human metabolites of pharmaceuticals, and may be used directly to install a C-F bond to block metabolic hotspots. A charge-transfer interaction between the reagent bis(methanesulfonyl) peroxide and the substrate arenes may be relevant for the chemoselective functionalization of arenes over other functional groups.

ALKYNE COMPOUNDS AS S-NITROSOGLUTATHIONE REDUCTASE INHIBITORS

Provided are compounds of formula (Ia) and pharmaceutically acceptable salts thereof, wherein A, B, R 1, R 2, m and n are as defined herein, which are active as inhibitors of S-Nitrosoglutathione reductase (GSNOR). These compounds prevent, inhibit, or suppress the action of GSNOR and are therefore useful in the treatment of GSNOR mediated diseases, disorders, syndromes or conditions such as, e.g., pulmonary hypertension, acute respiratory distress syndrome (ARDS), asthma, bronchospasm, cough, pneumonia, pulmonary fibrosis, interstitial lung diseases, cystic fibrosis and chronic obstructive pulmonary disease (COPD).

Chromatography-Free and Eco-Friendly Synthesis of Aryl Tosylates and Mesylates

Two chromatography-free and eco-friendly protocols have been developed to synthesize aryl tosylates and mesylates by the tosylation and mesylation of the corresponding hydroxyarenes, respectively. These protocols are superior to other known ones regarding

Synthesis of substituted indoline and carbazole by benzyne-mediated cyclization-functionalization

A benzyne-mediated synthesis of substituted indolines and carbazoles was developed. The reaction includes generation of benzyne using Mg(TMP) 2·2LiCl as a base, cyclization, and trapping the resulting organomagnesium intermediate with an electr

Scope of direct arylation of fluorinated aromatics with aryl sulfonates

The scope and limitations of direct arylation of fluorinated aromatics with aryl sulfonates was examined. Pd(OAc)2, in the presence of MePhos and KOAc in THF, efficiently catalyzed the direct arylation of fluoro aromatics with aryl triflates un

Mechanistic insight into the formal [1,3]-migration in the thermal claisen rearrangement

The thermal formal [1,3]-sigmatropic shift of allyl aryl ethers has been studied in depth experimentally with the aid of the density functional theory (DFT) calculations of the B3LYP function. Three mechanistic possibilities, referred to as the radical, ionic, and concerted mechanisms, have previously been put forth to explain the thermal [1,3]-rearrangement process. However, the intercrossing and radical trapping experiments indicate the rearrangement is an intramolecular process. The computational studies reveal that the concerted C[1,3]-sigmatropic shift suffered from a higher energetic barrier to allow the rearrangement to proceed under the conditions used. However, a tandem O[1,3]-sigmatropic shift with a configuration inversion of the oxygen atom and [3,3]-sigmatropic shift (the Claisen rearrangement) is the most likely pathway for the formal [1,3] rearrangement. Furthermore, the rearrangement experiments with a designed optically active substrate and O[1,3]-sigmatropic shift examples verify the new cascade rearrangement. In addition, computational and experimental studies indicate that water molecule assists the proton shift during the isomerization. The combined methods provide the new insight into the mechanism of the thermal formal [1,3]-migration in the Claisen rearrangement and the novel O[1,3]-sigmatropic shift as well.

Total synthesis of dictyodendrin A and B

(Figure Presented) In-do-line of fire: A highly efficient total synthesis of the title compounds features a novel benzyne-mediated one-pot indoline formation/cross-coupling sequence for the construction of a highly substituted key indoline intermediate. The peripheral substituents were then introduced onto the intermediate in a modular fashion to complete the total syntheses of dictyodendrin A and B.

Pitfalls in assessing the α-effect: Reactions of substituted phenyl methanesulfonates with HOO-, OH-, and substituted phenoxides in H2O

Toward resolving the current controversy regarding the validity of the α-effect, we have examined the reactions of Y-substituted phenyl methanesulfonates 1a-1l with HOO-, OH-, and Z-substituted phenoxides in the gas phase versus solu
