Substitued 3-(5-nitro-2-furyl)benzoindolizines III-XII were synthesized by a 1,3-dipolarcycloaddition of the ylide II formed in situ from N-(5-nitro-2-furfuryl)isoquinolinium bromide (I) and dimethyl butinedioate,diethyl buthenedioate,1-nitro-2-phenylethylene,ethyl 2-propenoate,ethyl 3-(5-nitro-2-furyl)-2-propenoate,1,3-diphenyl-2-propinone,2-propenenitrile,l-phenyl-3-(5-nitro-2-furyl)-2-propenone,and methyl 2-cyano-3-(4-nitrophenyl)-2-propeonate.Structure of these products was verified by spectral evidence.
