This molecule starts with a carbamate group (-C(=O)-O-) in which the oxygen bears an ethyl substituent. The carbamate carbon connects to a nitrogen that is part of a substituted pyrrolidine-a saturated five-membered ring containing one nitrogen and four carbons. In the pyrrolidine, the carbon adjacent to the nitrogen (ring position 2) is a chiral center with S configuration. This chiral carbon is directly bonded to a second five-membered ring composed of two nitrogens and three carbons, arranged as N1-N2-C3-C4-C5. Within this second ring, the two adjacent nitrogens (N1 and N2) each bear a single hydrogen. The chiral center is attached to C4 of this ring. Additionally, C3 carries an exocyclic double bond to a nitrogen, and C5 is double-bonded to C4.
