Drawing stereocenters

  1. Draw a chiral molecule.


  2. Click on (select) the asymmetric carbon atom that you want to configure as S or R.

  3. Right-click onto the carbon atom pops up the Atom Menu.

  4. Choose Stereo > R/S and the appropriate configuration.


  5. The relevant bonds will change automatically according to the proper R or S configuration.


  6. To display the stereo label on the asymmetric carbon atom, select View Menu > Stereo > R/S Labels > All.

  7. The configuration of the asymmetric carbon atom is displayed in parentheses: images/download/attachments/48075937/Draw_stereo5.PNG

To remove the stereo label from the the asymmetric carbon atom, choose View Menu > Stereo > R/S Labels > None.

To delete stereo representation, right-click on the asymmetric carbon atom and choose Atom menu > Stereo > R/S > Off.
