The alkali metal salts of the polycyclic hydroxy-ketones 7 and 8 rearrange by intramoleculartransfer of hydride between alkoxide and carbonyl carbons. Rates in DMSO solution, determined by dynamic 1H NMR methods, show strong concentration dependence, increasing with dilution of the alkoxides. Rates are also strongly cation dependent, increasing in the order Li
