Prostanoids: LXXIV. 2,3-Dichloro- 4,4-ethylenedioxy-2-cyclopentenone in the Synthesis of Analogs of Marine Prostanoid

Transformations of readily accessible 2,3-dichloro-4,4-ethylenedioxy-2-cyclopentenone resulted in formation of previously unknown 2,3-dichloro-4-hydroxy-4-[(Z)-2-octenyl]-2-cyclopentenone which is a universal block synthon for analogs of marine prostanoids.
