Enantioenriched beta-lactams are accessed via enantioselective allylation of anilines with Morita-Baylis-Hillman carbonates followed by a base-promoted cyclization. The resulting 3-methyleneazetidin-2-ones are amenable to diastereoselective functionalization to produce analogues of biologically active beta-lactams. The use of nearly equimolar quantities of the starting materials make this method efficient and straightforward.
