The title compound was synthesized by AdNE addition of II-octyl cuprate to 2,3-dichloro-4,4-ethylcnedioxy-2-cyclopentenone, followed by alcoholysis and reduction with NaBH4.

Reaction of a number of 3-N-, O-, S-, Cl-, and alkyl-substituted 2-chloro-4,4-ethylenedioxycyclopent-2-en-1-ones with Zn in NH4Cl-MeOH medium were investigated. The expected or partially transformed dehydrochlorination products were isolated. An exclusive chemical stability of 3N-containing cyclopentenones was disclosed. This phenomenon was understood as originating from stabilizing n-d-p-interaction of electrons belonging to heteroatoms in the planar C ' (O)-C-2(Cl)-C-3(N) fragment contained in the molecules of the compounds.
