WebDevelopment. The thalidomide molecule is a synthetic derivative of glutamic acid and consists of a glutarimide ring and a phthaloyl ring (Figure 5). Its IUPAC name is 2-(2,6-dioxopiperidin-3-yl)isoindole-1,3-dione and it has one chiral center After thalidomide's selective inhibition of TNF-α had been reported, a renewed effort was put in …
WebLet's apply our chirality discussion to real molecules. Consider 2-butanol, drawn in two dimensions below. Carbon #2 is a chiral center: it is sp 3-hybridized and tetrahedral (even though it is not drawn that way above), and the four substituents attached to is are different: a hydrogen (H) , a methyl (-CH 3) group, an ethyl (-CH 2 CH 3) group, and a hydroxyl … WebThe enantiomers of thalidomide were determined by direct resolution on a tribenzoyl cellulose column.
