I'm having trouble understand what sections of the molecule morphine relate to what sections of its corresponding IUPAC name of (4R,4aR,7S,7aR,12bS)-3-methyl-2,4,4a,7,7a,13-hexahydro-1H-4,12-methanobenzofuro[3,2-e]isoquinoline-7,9-diol. One problem is I believe to have numbered the carbons in the correct order, although the name uses '12bS', which isn't included within my numbering.

Is anyone able to point me in the direction for learning how the name relates to the structure?

Here is my numbering of the chiral centres;

  • $\begingroup$ I have a déjà-vu; I’m certain I added italics to the IUPAC name of morphine not too long ago … o.o $\endgroup$ – Jan Oct 15 '19 at 4:59
