Abstract
Substituted 3-furylbenzoindolizines V-X were prepared via 1,3-dipolar cycloaddition of yields generated from the furan-related N-onium salts I-IV to dimethyl butinedioate, ethyl 3-(5-nitro-2-furyl)-2-propeonate, 1-phenyl-3-(5-nitro-2-furyl)-2-propenone, and 1-phenyl-2-nitroethylene. Structure of the compounds synthesized was confirmed by spectral data.
