Synthesis of functionalized cyclobutene derivatives via selective sN2' reaction of dichlorocyclobutenes

Dichlorocyclobutenone acetals, available via the cycloaddition of dichloroketene and alkynes followed by acetalization, undergo selective SN2' attack by various nucleophiles to give a variety of functionalized cyclobutene derivatives in high yi
