Novel stereoselective synthesis of alpha-methylene-beta-substituted pyroglutamates, and alpha-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. (C) 2011 Elsevier Ltd. All rights reserved.
