Acyl sulfonamide, peri-substituted, fused bicyclic ring compounds useful for the treatment or prophylaxis of a prostaglandin-mediated disease or condition are disclosed. The compounds are of the general formula
A representative example is:
A study of the double bond reactivity in Δ3-cyclohexene derivatives with one polar substituent in the side chain and Me substituents in the ring has shown that the preferred conformation for these compounds, indepenent of their stereochemistry, has the polar group axial, giving rise to supra-annular interaction. Such interaction decreases the nucleophilicity of the ring double bond. A similar study
The present invention relates to processes for preparing certain 2-pyridones and 2-pyridinols, to novel compounds of these two types and to their use as biologically active compounds, in particular for controlling harmful microorganisms in crop protection, in the medicinal field and in the protection of materials.
aerobic oxidation of terminalalkenes in toluene into the corresponding methyl ketones in the presence of a catalytic amount of pyridine using propan-2-ol as a reductant and molecularoxygen as an oxidant. Two catalytic cycles sharing a Pd(II)–OOH species are proposed. One is the formation of a Pd(II)–H species in the oxidation of propan-2-ol to acetone, followed by reaction with molecularoxygen to give
