3-Vinyl-2,5-dihydrothiophene 1,1-Dioxide: A Novel, Easily Accesible, High-yielding Precursor to Dendralene, the Simplest Representative of the Diene-transmissive Polyenes

Cheleotropic extrusion of SO2 from readily prepared 3-vinyl-2,5-dihydrothiophene 1,1-dioxide 2 provides a clean and efficient route to dendralene (3-methylenepenta-1,4-diene 1), the simplest member of the diene-transmissive polyenes, which contrary to previous reports is a stable, easily handed compound that shows unexpected selectivity in Diels-Alder cycloadditions, thus enhancing its utility as a tandem annelating reagent.

Structure-activity studies of cyclic ketone inhibitors of the serine protease plasmin: Design, synthesis, and biological activity

Three series of cyclic ketone inhibitors were synthesized and evaluated against the serine protease plasmin. Peptide inhibitors that incorporated 3-oxotetrahydrofuran and 3-oxotetrahydrothiophene 1,1-dioxide groups had the highest activities. Alkylamino substituents, which were designed to bind in the S1 subsite of plasmin, were attached to the inhibitors. Compounds 5c and 5g, which incorporated 6-aminohexyl substituents, were found to be optimal and demonstrated IC50 values in the low micromolar range. Incorporating conformationally constrained peptide segments into the inhibitors did not improve their activities.

Toward the synthesis of novel fluorinated building blocks: 3,4-difluorothiophene-1,1-dioxide

Addition of elemental fluorine to 2,5-dihydrothiophene-1,1-dioxide (4) provided a mixture of isomeric 3,4-difluoro-2,3,4,5-tetrahydrothiophene-1,1-dioxides (5) in moderate yield. Photochemical chlorination of each of these isomers gave the same product mixture consisting mainly of trans-3-chloro-3,4-difluoro-2,3,4,5-tetrahydrothiophene-1,1-dioxide (9a) and trans-3,4-dichloro-3,4-difluoro-2,3,4,5-tetrahydrothiophene-1,1-dioxide (11b). Dehydrohalogenation of the former gave 3,4-difluoro-4,5-dihydrothiophene-1,1-dioxide (12) as the main product, whereas dehydrohalogenation of the latter gave 3,4-difluorothiophene-1,1-dioxide (3) as the main product.

CHEMICAL REPERCUSSIONS OF ORBITAL INTERACTIONS THROUGH BOND AND THROUGH SPACE. THE REACTIVITY OF THE DOUBLE BOND IN UNSATURATED CYCLIC SULPHONES TOWARDS AZIRIDINE FORMATION AND EPOXIDATION

The ease of formation of aziridine and/or epoxides from a series of bicyclic olefins, where distant sulphonyl groups are present, is very variable.There is some correlation between reactivity of the vinyl group and its ?-ionisation potential which is high in the present molecules relative to comperison olefins.This increase is thought to be due to the presence of orbital interactions through bonds and/or through space between the sulphone group and the double bond, making the latter electron deficient.The ionisations potentials were determined by UV-photoelectron spectroscopy and the assignments made by recourse to ab initio configuration interaction methods.

Oxygen-17 Nuclear Magnetic Resonance Spectral Investigation of 3-Alkoxy-trans-3,4-Disubstituted-Thiolane 1,1-Dioxides and Related Compounds

The (17)O NMR spectra of 3-alkoxythiolane 1,1-dioxides indicate that the sulfonyl oxygens are diastereotopic but their chemical shift differences are essentially independent of the structure of the alkyl group in the alkoxy moiety.Eu(fod)3 enhances the (17)O chemical shift difference between the diastereotopic sulfonyl oxygens in 3-isopropoxythiolane 1,1-dioxide and shifts both oxygens upfield. α,β-Unsaturation deshields the sulfonyl oxygens in both five- and six-membered rings.
