A four-electron electrocyclic ring-opening/intermolecular [4+2] cycloaddition of α-hydroxycyclobutenones is reported. The reaction represents the first example for the intermolecular cycloaddition of the extensively studied enol-ketene intermediate, and provides a new synthetic route to multiply substituted δ-lactams in high stereoselectivity.

A systematic study of the reaction of 4-hydroxycyclobutenones with thionyl chloride is reported.A useful model evolves from this study which allows the prediction of the site of chlorination for unsymmetrical examples.The chlorination is envisaged to invo
