Thiazoline is a heterocyclic compound containing both sulfur and nitrogen in the ring. Although thiazoline itself is rarely encountered, its derivatives are often bioactive. For example, in a common post-translational modification, cysteine residues are converted into thiazolines.
Three related classes of C3NS heterocycles are well studied, 1,3-thiazoles (parent: C3H3NS), 1,3-thiazolines (parent: C3H5NS), and 1,3-thiazolidines (parent: C3H7NS). The naming is analogous to the C3N2 heterocycles, imidazoles, imidazolines, and imidazolidines.
Thiazolines found in nature
In a recent study, thiazolines were identified in nature through an analysis of sesame seed oil. The toasted sesame seed oil was extracted using a Solvent-Assisted Flavor Evaporation technique. The extract was analyzed by GC and GC-MS and a total of 87 components were identified. Amongst these components, 2-ethyl-4-methyl-3-thiazoline and 2-isopropyl-4-methyl-3-thiazoline were identified and confirmed as being present in a natural product for the first time.
