Synthesis of N,N ‘-linked bisazaheterocycles with sulfonamide structure via oxidation of S,N-heteroaromatic cations

N-Phthalimidyl- and N-quinazolinyl-substituted 3-hydroperoxy-, 3-hydroxy- and 3-oxoisothiazole 1,1-dioxides have been synthesized by the sequence of oxidation reactions from N,N’-linked isothiazolium perchlorates with hydrogen peroxide, MMPP, and pyridinium dichromate. Isothiazolium salts without acceptor substituents did not give N-substituted sultams. Novel N,N’-bisazaheterocycles were investigated as inhibitors of acetylcholinesterase (AChE) and human leukocyte elastase (HLE). Two 2,3-dihydro-3-hydroperoxy-2-(phthalimid-1-yl)isothiazole 1,1-dioxides were found to inhibit AChE.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 383-29-9 is helpful to your research. Product Details of 383-29-9.

Selective Aza Diels-Alder and Domino [4+2]/[2+2] Cycloaddition Reactions of Arynes with N-Sulfonyl Ketimines

Transition-metal-free inverse electron-demand aza Diels-Alder and domino [4+2]/[2+2] cycloaddition reaction of arynes and N-sulfonyl ketimines has been demonstrated. This novel, mild, and efficient protocol allows rapid access to isothiazole dioxide-fused dihydroquinoline or dihydrocyclobutaquinoline derivatives selectively by simply varying the equivalents of aryne precursors. The application of this method has been amply illustrated in the synthesis of 2,4-diarylquinolines.

Isothiazoles as active-site inhibitors of HCVNS5B polymerase

Isothiazole analogs were discovered as a novel class of active-site inhibitors of HCV NS5B polyrnerase. The best compound has an IC50 of 200 nM and EC50 of 100 nM, which is a significant improvement over the starting inhibitor (1). The X-ray complex structure of I with HCV NS5B was obtained at a resolution of 2.2 angstrom, revealing that the inhibitor is covalently linked with Cys 366 of the ‘primer-grip’. Furthermore, it makes considerable contacts with the C-terminus, P-loop, and more importantly, to the active-site of the enzyme. The uniqueness of this binding mode offers a new insight for the rational design of novel inhibitors for HCV NS5B polymerase. (c) 2006 Elsevier Ltd. All rights reserved.

Accessing Enantiopure Endocyclic Sulfoximines Through Catalytic Cycloisomerization of Oxygenated Propargyl-Sulfinamides

In this study, a novel strategy to access endocyclic sulfoximines in an enantiopure form is reported. The approach is based on a silver nitratecatalyzed cyclo-isomerization reaction of oxygenated propargylic sulfinamides and provides efficiently 5-membered endocyclic sulfoximines (isothiazole 1-oxide). These new heterocyclic scaffolds can be isolated or directly converted into cyclic sulfinamides via Lewis acid-mediated sulfur dealkylation reactions.
