Novel stereoselective synthesis of α-methylene-β-substituted pyroglutamates, and α-alkylidene-pyroglutamates has been achieved via substrate controlled asymmetric alkylation of l-threonine derived oxazole with Baylis-Hillman reaction based allyl bromides and acetates, respectively. The synthesized compounds were evaluated for their proteasome inhibition and cytotoxicity on multiple myeloma cells.
