Formation of Unsaturated Esters in the Single Electron Transfer Reaction of Cyclopropanone Acetals with Quinones under Non-irradiated Conditions
Unsaturated esters were formed from cyclopropanone aceytals in the reaction with DDQ or chloranil, where ring-opened C-C and C-O bonded adducts were the intermediates formed via a SET mechanism resulting in the ester formation.

Prostaglandins and Prostaglandin Intermediates. 22 - Synthesis of a Stable Prostacyclin Analogue
An industrially available prostaglandin intermediate is converted into a new prostacyclin analogue with a cyclic ether instead of the unstable enol ether system.For the construction of the modified alkyl side chain two subsequent Horner olefinations are used.This reaction sequence includes a new methodology for the conversion of an aldehyde into a β,γ-unsaturated carboxylic acid by a three-carbon elongation.
