A simple phenylation of the 5,11‐diazatetracyclo[6.2.2.0 2,7 0 4,9 ]dodecane system (5,11‐diazaditwistane) is described. Phenylative decarboxylation of 5,11‐biscarbethoxy‐5,11‐diazatetracyclo[6.2.2.0 2,7 .0 4,9 ]dodecane‐2,9‐dicarboxylic acid ( 3 ) with lead tetraacetate in benzene affords the 2,9‐diphenyl analogue ( 4 ). Hydrolysis yields 2,9‐diphenyl‐5,11‐diazatetracyclo‐[6.2.2.0 2,7 .0 4,9 ]dodecane ( 5 ), whereas lithium aluminum hydride affords the 5,11‐dimethyl analogue ( 6 ).
