Chiral Centers (Stereocenters) in a ring?
« on: April 15, 2009, 04:05:02 PM »


My book says a carbon atom in a ring (like cyclohexane) is a chiral center if:

1) It bears two different substituents on the outside of the ring
and
2) The path traced from that carbon in one direction is different from the path traced in the other direction

I understand the first requirement, it is simple enough but what do they mean by 2)

Could you please give an example? Thanks!

Counter examples to 2 would be any 1,4- or 1,1-disubstituted cyclohexane.

to be honest i dont even know what the 2nd requirement means. the 1st one got me through organic 1 and 2 quite easily enough...essentially, as long as the center in question is attached to alll different substituents, it is a chiral center.
