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

Diastereomerically pure 2-cyclopropylglycines 2, 2′-substituted with an electron-withdrawing group, were prepared in two steps by Michael addition of the glycine equivalent 2-(diphenylmethyleneamino)acetate 11 to various Michael acceptors of type 1 with subsequent γ-elimination of bromide and followed by acid mediated deprotection.
