Abstract

A green radical synthesis method for pyranopyrazole scaffolds catalyzed by a PCET (proton-coupled electron transfer) photocatalyst in an aqueous media in an air environment, at rt, and under a blue LED as a renewable energy source. The goal of this effort is the use of novel, widely available, and affordable donor-acceptor (D-A) fluorophores. The rapid and easy-to-use photocatalyst based on carbazoles; (4CzIPN) produces excellent results, uses little energy, and safeguards the environment. This makes it feasible to study the historical evolution of the environment and its chemical constituents. Gram-scale cyclization further indicates suitability for industrial applications.

Graphical Abstract

Radical Knoevenagel-Michael cyclo condensation reactions were used to create pyranopyrazole scaffolds. The proton-coupled electron transfer method of photosynthesis was employed to catalyze the reaction utilizing the novel donor-acceptor fluorophore; 4CzIPN. A renewable energy source using blue LED in an aqueous medium is used at room temperature and in an air environment.
