Stereocenter in Aromaticity
« on: December 16, 2010, 02:07:22 PM »
hey everyone,

I have a question...
how can you determine the stereocenters in a ring form compound?? is it the same like in a normal chain form?

thanks in advance :)

If its a cycloalkane type structure then yes, its the same rules.  However, aromatic systems aren't chiral.  There are odd cases of chiral binapthyl systems (BINAL-H and the like) which are chiral due to rotation barriers and go by R/S nomenclature but its established by walking one end of the molecule and falling down.  If you do so going to the right of the molecule its R and to the left its S (this is how I think of it).
