Abstract

The convergence of supramolecular chemistry and polymer science especially porphyrin chemistry offers many powerful approaches for building functional nanostructures with welldefined dynamic behavior. The efficient metal-free three-component reactions to synthesize 1,4,5-trisubstituted 1,2,3-porphyrin-triazoles from available materials, such as porphyrin-aldehydes, nitroalkanes, and organic azides, and also from porphyrin aldehydes, nitroalkanes, and porphyrin azides is described. The process is enabled by an organocatalyzed (morpholine:p-toluenesulfonicacid) Knoevenagel condensation of the formyl group with the nitro compound, which is followed by the 1,3-dipolar cycloaddition of the azide to the activated alkene. The reaction features an excellent substrate scope, and the products are obtained with good yield and regioselectivity. This methodology was used for the synthesis of fused triazole heterocycles from nitroporphyrin and organic azides.
