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
