An efficient and straightforward one-pot synthetic protocol has been developed for the synthesis of 3-arylindolizine- 1-carboxylates via 1,3-dipolar annulation of 2-(2-nitro-1-arylethyl)malonates with pyridine and subsequent aromatisation in the presence of molecular iodine. The structure of methyl 3-(4-methoxyphenyl)indolizine-1-carboxylate (2a) and methyl 3-iodo-2-(4- nitrophenyl)indolizine-1-carboxylate (2f) was further confirmed by X-ray single crystal analysis.
