Treatment of pentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11-dione with aqueous sodium cyanide produced 8,11-dihydroxy-pentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11-lactam. -11-Cyano-11-hydroxypentacyclo[5.4.0.02,6.03,10.05,9]-8-undecanone and 5-cyano-4-oxahexacyclo-[5.4.1.02,6.03,10.05,9.08,11]-5-dodecanol were isolated as intermediates. Structures were elucidated from extensive 1H and 13C n.m.r.
