AbstractAn iodine-promoted synthesis of acylindolizinecarboxylates via 1,3-dipolar cycloaddition of nitrogen ylides with acetylenecarboxylates and subsequent aromatization for the generation of a wide range of structurally interesting, pharmacologically and photoelectrically significant compounds is reported. Only readily available materials, mild conditions, and operationally trivial reaction protocols
