Ring Enlargement with Diazomethane: Studies on Bridged Tricyclic 1,2-Diketones Based on Bicycloheptane/Bicyclooctane Systems Derived from Longifolene

A comparative study of the ring enlargement by diazomethane of the bridged tricyclic 1,2-diketones based on bicycloheptane/bicyclooctane systems derived from longifolene, viz. longibornane-10,11-dione (longicamphorquinone, 4)/longihomocamphenilane-7,8-dione (longidione, 5) reveals a striking contrast.While 4 undergoes a facile ring homologation, 5 remains unchanged under the same conditions.The resulting isomeric keto-enol ethers 8/9 from 4, hydrolysable by acid to longihomocamphorquinone (12), have been further transformed into α,β-unsaturated ketones 10/11 by LAH reduction.
