Reduction of 11-oxo-10-oxapentacyclo4,13.02,7.06,12>pentadecane (lactone I) and 10-oxo-11-oxapentacyclo4,13.02,7.06,12>pentadecane (lactone II) with lithium aluminium hydride aforded 4-hydroxymethyl-12-hydroxytetracyclo2,7.06,11>tridecane (diol III) and 4-hydroxy-12-hydroxymethyltetracyclo2,7.06,11>tridecanone (diol IV).Diol III reacted with concentrated phosphoric acid to give 3-methyltetracyclo2,6.05,10>tridecanone-9 (V) as practically the sole product.Diol IV afforded a complex mixture of products in which were identified 2-methyl-3-oxadiadamantane (VI; 57percent), 10-oxa-2(3)-homodiadamantane (VII; 20percent), 3-hydroxydiamantane (VIII; 3percent), diadamantane (X; 7percent) and diadamantanone (IX; 2percent).
