Stereoselective allylation of 4-oxoazetidine-2-carbaldehydes. Application to the stereocontrolled synthesis of fused tricyclic β-lactams via intramolecular Diels-Alder reaction of 2-azetidinone-tethered trienes

Allylation reactions of racemic and optically pure 4-oxoazetidine-2- carbaldehydes were investigated both under anhydrous conditions and in aqueous media. Different Lewis acid or metal mediators showed varied diastereoselectivities on product formation du
Rapid entry to enantiopure polycyclic β-lactams via intramolecular nitrone-alkene cycloaddition of 2-azetidinone-tethered alkenylaldehydes

New enantiomerically pure fused 2 or bridged 3 polycyclic β-lactam systems are regio- and stereoselectively prepared via intramolecular nitrone- alkene cycloaddition of 2-azetidinone-tethered alkenyl-aldehydes 1. The regioselectivity of the cycloaddition
