title: Regio- and stereocontrolled metal-mediated carbonyl propargylation or allenylation of enantiomerically pure azetidine-2,3-diones: synthesis of highly functionalized 3-substituted 3-hydroxy-beta-lactams
abstract: Regio- and stereocontrolled metal-mediated Barbier-type reactions of azetidine-2,3-diones with differently substituted propargyl bromides offer an efficient asymmetric entry to densely functionalized 3-propargyl- (or allenyl-) substituted 3-hydroxy-beta-lactams.
