A new rearrangement byproduct, 3-methyl-1,2,3,4,4a,4b,9a,15,15a,15b-decahydro-(4,5);(4a,15)-dimethanotricyclo-(4,3,1,0 2,7 )deca[8,9,1,10-a,b,c]pyrido[4,3-a]-acridin-6-en-9-ol-8-one, has been isolated from the acid-catalyzed O-demethylation of 7a-o-aminophenyl-6,14-endo-ethenotetrahydrothebaine. The
