An efficient one-pot synthesis of functionalized thiazolines via the coupling of thioamides with 4-bromocrotonate esters is described. A range of aryl- and alkyl-thioamides with various substitutions are well-tolerated. Additionally, the presence of the exocyclic ester functionality provides a convenient handle for the synthesis of more complex thiazoline-containing natural products and biologically-relevant
