Abstract (EN): Condensation adducts of the Ni(II) and Cu(II) complexes of beta-amino-meso-tetraphenylporphyrin with dimethyl acetylenedicarboxylate (DMAD) and diethyl ethoxymethylenemalonate were converted into the corresponding esters of pyridinone-fused porphyrins by using three different cyclization protocols: conventional heating, microwave irradiation, and Eaton's reagent. High yields in a short period of time were obtained by using file microwave-irradiation protocol under closed-vessel conditions. The structure of the copper(II) complex of pyridinone-fused porphyrin was confirmed by X-ray crystallography.
