Dipipanone & Methadone Metabolites

[scriptx]

Do you guys and gals think it is likely that these two closely-related compounds will both form the same metabolites?

For example, methadone produces EDDP and since dipipanone is so similiar would dipipanone also produce EDDP?

Dipipanone/Diconal: 4,4-diphenyl-6-(1-piperidinyl)-heptan-3-one
Methadone: (RS)-6-(Dimethylamino)-4,4-diphenylheptan-3-one

EDDP is 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine and it is formed from self-condensation of N-desmethyl methadone to the enamine. So no it would not be formed from dipipanone.
