The invention generally relates to methods and compounds for treating proliferative disorders, viral infections, or both. In some embodiments, the invention provides an anticancer or antiviral compound including a substituted nitro phenoxy phenyl, a sulfonylurea, and an alkyl group. In some embodiments, the invention provides a method of treating a proliferative disorder or a viral infection including administering an anticancer or antiviral compound that binds to a thromboxane receptor, has preferential binding for either TPalpha (TPα) or TPbeta (TPβ) receptor subtype.

Diketones are regioselectively prepared from alkynyl ketones under mild conditions by palladium catalysis; 5-heptyn-2-one and 2-(2-nonynyl)cyclohexanone give 1,4-dikektones whereas 2-(2-heptynyl)cyclopentanone and 5,6-didehydroprostaglandin E2 methyl ester afford 1,5-diketones.

described to access a range of polycyclic and highly oxygenated carbocycles. First developed in an approach to the synthesis of ryanodol, metallacycle-mediated annulative diketone–alkyne coupling defines a framework for realization of new retrosynthetic relationships for complex molecule synthesis. In addition to demonstrating this reaction in the context of forging distinct carbocyclic systems, including
