1 Introduction Pyran derivatives are among the most important heterocyclic compounds due to their broad applications in medicinal chemistry and biological fields such as anticancer, antimicrobial, anti-inflammatory, antioxidant, antiviral, antidiabetic, antimalarial, antitubercular, antifungal, and antiparasitic activities [1-13], highlighting their significance in drug development.

Abstract Phthalocyanines and porphyrins are often the scaffolds of choice for use in widespread applications. Synthetic advances allow bespoke derivatives to be made, tailoring their properties. The selective synthesis of unsymmetrical systems, particularly phthalocyanines, has remained a significant unmet challenge. Porphyrin‐phthalocyanine hybrids offer the potential to combine the favorable features of both parent structures, but again synthetic strategies are poorly developed.
