tricyclic alcohol 4 in almost quantitative yield. Lithium aluminium hydride reduction of oxide 2 gives a mixture of the same alcohol 4 and the rearranged, bicyclic alcohol5. Vapour phase chromatography of oxide 2 under most conditions effected acid catalysed isomerization of 2 to the bicyclic aldehyde 6 which was oxidized to the known carboxylic acid 7 as proof of structure. Above 120°, aldehyde 6 is converted
