Convenient Route to Super-Expanded Calixpyrroles:  Synthesis of Calix[n]furano[m]pyrroles (n = 3, 4, 6, 8 and m = 2, 4)

meso-Alkylporphyrinogen-like cyclic oligomers containing furans and pyrroles have been synthesized by “3 + 2” and “4 + 2” approaches. Condensation of 5,5,10,10,15,15-hexaethyl-21,22-dioxatetrapyrromethane with 2,5-bis[(α-hydroxy-α,α-dimethyl)furan] resulted in the formation of cyclic hexamer and cyc...

Summary:meso-Alkylporphyrinogen-like cyclic oligomers containing furans and pyrroles have been synthesized by “3 + 2” and “4 + 2” approaches. Condensation of 5,5,10,10,15,15-hexaethyl-21,22-dioxatetrapyrromethane with 2,5-bis[(α-hydroxy-α,α-dimethyl)furan] resulted in the formation of cyclic hexamer and cyclic dodcamer. Effects of catalysts, temperature, inorganic additives, solvent, and reaction concentration were examined.
