 Title    Bicyclo[2.2.2]octane-2-spirocyclohexanes, Part 2 [1] Reduction Products of Spirodiisophora-3',6-dione  
 Abstract    The reduction o f spirodiisophora-3',6-dione under various conditions occurs exclusively at its 3'-keto-function in the cyclohexane ring. The action o f lithium aluminium hydride yields the 3'-eq-hydroxyketone, while catalytic hydrogenation, hydroboration and the action o f metal borohydride produces the 3'-ax-epimer. The conformers give rise to pairs o f distinct epi­ meric functional derivatives. Anhydrous hydrazine removes the 3'-oxygen function o f the 3',6-dione entirely, with formation o f spirodiisophor-6-one. Catalytic hydrogenation o f the 3'-oxim ino-6-ketone yields the corresponding 3'-amine. The ,3C N M R spectra o f the individu­ al products are assigned and correlated with their structures.
