The pyridinium bromides 2a,b reacted with dimethyl acetylene-dicarboxylate (DMAD) to give the indolizine derivatives 6a,b. Bromide salts 2a,b reacted also with β-nitrostyrene, ethyl acrylate and with acrylamide to give the corresponding indolizine derivatives 8a,b and 10a-d. Reaction of the quinolinium salts 12a,b with DMAD, β-nitrostyrene and with ethyl acrylate as dipolarophiles furnished the corresponding

A library of hitherto unknown functionalized and annulated spiro[indoline-3,1`-indolizin]-2-one derivatives incorporating thiophene moiety has been synthesized under conventional and microwave irradiation conditions. The structures, regio and diastereoselectivity of the synthesized cycloadducts have been confirmed using different analytical and spectral tools.
