Hydroximic acids of 7-oxabicycloheptane substituted ether and thioether prostaglandin analogs are provided having the structural formula ##STR1## wherein Y is O or ##STR2## and including all stereoisomers thereof. The compounds are inhibitors of prostaglandin and biosynthesis and as such are useful, for example, as anti-allergy and antiinflammatory agents and also as antipsoriatic agents.

The electrochemical conversion of unactivated carboxylic acids to olefins under alternating polarity is reported. By modulating electrode surface quality and local acidity, chemoselective Hofer-Moest reactivity is realized on conventionally difficult substrates, including primary and secondary unactivated carboxylic acids. This simple protocol is exceptionally scalable (1 kg) and cost-effective.

catalyst-controlled stereoselective olefinmetathesis considerably. By incorporation of commercially available Z-butene together with robust and readily accessible Ru-based dithiolate catalysts developed in these laboratories, a large variety of transformations can be made to proceed with terminal alkenes, without the need for a priori synthesis of a stereochemically defined disubstituted olefin. Reactions thus proceed
