Swem oxidation of 8,16-dimethoxy- and 8,16-dimethyl-5,13-di-t-butyl- l,2,9,10-tetrahydroxy[2.2]metacyclophane, 1 and 2, afforded 5,13-di:t-butyl- 10-hydroxy-8,16-dimethoxy[2.2]metacyclophane-1,2,9-trione 3 and 4. By subsequent oxidation with DDQ, 8,16-dimethoxy- and 8,16-dimethyl-5,13-di-t- butyl[2.2]metacyclophane-1,2,9,10-tetraones, 5 and 6, were obtained.
