Abstract
The invention relates to the stereoisomers of novel cyclopentene derivatives and to the preparation thereof. The cyclopentene derivatives are obtained by cycloaddition reaction between cyclopentadiene and a mono-or bis-thioalkyl (or aryl) ketene and reaction between the obtained product and a nucleophile agent. The compounds of the invention are intermediate products valuable for the preparation of different compounds, among which compounds of the prostaglandin type.
