Begin with a central tetra-coordinate carbon. This carbon is:
- Singly bonded to a hydroxyl group.
- Singly bonded to a phenyl ring (no substituents on the ring).
- Double-bonded to a nitrogen.
The nitrogen is then singly bonded to a chiral tetrahedral carbon. At this chiral carbon (R-configuration):
- One substituent is a cyclopropyl ring (a saturated three-carbon ring).
- The other substituent is a five-membered tetrazole ring (composed of one carbon and four nitrogens), attached through its carbon atom.
On the tetrazole ring, the ring nitrogen at the beta position of the chiral carbon bears a substituent consisting of a two carbon chain:
- The first carbon is bonded to the ring nitrogen.
- The second carbon is bonded to a hydroxyl group and is double-bonded to another nitrogen.
- The latter nitrogen (in turn) is bonded to a three-carbon fragment ending in a vinyl group, forming a -C-CH=CH2 substituent.
