Diastereoselective route to novel fused or bridged tricyclic β-lactams through intramolecular nitrone-alkene cycloaddition of 2-azetidinone-tethered alkenylaldehydes - Synthetic applications to carbacephams and cyclic β-amino acid derivatives

A convenient, regio- and stereoselective direct route to optically pure unusually fused or bridged tricyclic β-lactams has been developed by use of intramolecular nitrone-alkene cycloaddition (INAC) reactions of easily available monocyclic 2-azetidinone-t
