Abstract

Procedure for obtaining a bicyclohetene-7-carbaldehyde, of formula: **(See formula)** in which R1 is a halogen atom and R2 is a cyano or carbamoyl radical, an alkoxycarbonyl radical of up to 6 carbon atoms or an N-alkylcarbamoyl radical in which the alkyl radical contains from 1 to 6 carbon atoms, as an intermediate in obtaining prostaglandins or prostaglandin-like compounds, characterized in that it comprises the isomerization of a bicyclohectene-7-anti-carbaldehyde, of the formula: **(See formula)** wherein R1 and R2 have the meanings indicated above.
