Iodine-promoted synthesis of acylindolizine derivatives from acetylenecarboxylates and pyridinium, isoquinolinium, or quinolinium ylides

An 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 were required. Graphical abstract: [Figure not available: see fulltext.]

Studies on 1,3-Dipolar Cycloaddition Reactions of Some Cycloimmonium Ylides

A wide variety of some new benzoindolizine derivatives have been synthesized by the interaction of quinolinium and isoquinolinium ylides generated in situ from their precursors with acetylenic dipolarophiles.Triethylamine in benzene media was used as the
