Problem #16: Click the mouse on each of the chiral carbons in the molecule shown below. Click the Help button for a short review on the requirements for chirality in organic molecules.


If you would like to know the total number of stereocenters in the molecule, click and hold the mouse button on the box below.













































All of the carbon indicated are chiral since they are bonded to four different groups.  These are most readily visualized by viewing the molecule as a whole, with different "branches" attached to each of the chiral centers.  Each of the chiral centers has one attached hydrogen, a bond to at least one heteroatom (nitrogen or sulfur) and two pathways proceeding in opposite directions around an unsymmetrical ring.
