grey=carbon; white=hydrogen; blue=nitrogen After assigning priorities, I concluded that the carbon attached directly to the nitrogen is an S enantiomer and the carbon attached directly to that carbon (the one not in a ring) is an R enantiomer. I decided to treat the benzene rings as substituents (phenyl groups). Thus, the longest carbon skeleton has three carbons. The carbon attached to the nitrogen is the number 1 carbon. I came up with the following name: (1S,2R)-1,2-diphenyl-1-propanamine Would you agree? Thanks.
