Problem: In clavulanic acid there is a carbon-atom that that has an oxygen-atom, a nitrogen-atom, and a carbon atom attached to it. Please show me how to assign the proper designation, R or S to this carbon atom.

Solution:

Please see the attached file for chemical diagrams.

Consider the chiral centers marked as 2 and 5 (the carbon which is connected to four different substituents)
The R and S designation is given as

(see attached for diagram)

Select the four ...
