Convenient preparative synthesis of pentacyclo[5.3.0.02,5.03,9.04,8]decane (C 2-Bishomocubane)

By reaction of pentacyclo[5.3.0.02,5.03,9.04,8]decane-6,10-dione 6-ethyleneketal with lithium aluminum hydride the corresponding hydroxyketal was obtained whose hydroxy group was replaced by chlorine at boiling in CCl4 in the presence of a 15% molar excess of triphenylphosphine. 6-Ethyleneketal of pentacyclo-[5.3.0.02,5.03,9.04,8]decan-6-one obtained by dechlorination of the chloroketal in a system lithium-t-BuOH in THF was hydrolyzed to ketone by heating in 10% sulfuric acid in the presence of THF. The obtained ketone was reduced along Wolf-Kishner reaction to pentacyclo[5.3.0.02,5.03,9.04,8]decane.

SYNTHESIS AND -CYCLOREVERSION OF CAGE KETONES

A series of pentacyclic cage ketones 2b-d having no substituent was synthesized by the photochemical -cycloaddition reaction of corresponding tricyclic dienones 1b-d.The cage ketones 2b-d underwent thermal -cycloreversion to give dienones 1b-d.The reactivities were dependent on the length of the bridge "X".
