Special Issue Information

Dear Colleagues,

In recent years, the field of organic synthesis has witnessed remarkable advancements, with photocatalysis emerging as a powerful tool for achieving efficient and sustainable chemical transformations. The utilization of light as an energy source in conjunction with catalytic systems has enabled the development of novel synthetic methodologies. Among these, photocatalytic cyclization reactions have garnered significant attention, offering a versatile approach for the construction of diverse heterocyclic compounds.

This Special Issue aims to highlight the latest breakthroughs in the realm of photocatalytic cyclization for the synthesis of heterocyclic compounds. The unique reactivity and selectivity afforded by photocatalysis have opened new avenues for the assembly of complex molecular structures, facilitating the exploration of diverse chemical space. Contributions to this issue encompass a broad spectrum of research, spanning innovative catalyst design, mechanistic insights, and applications of photocatalytic strategies to access a variety of heterocyclic motifs.

We invite researchers from academia and industry to share their cutting-edge findings, methodologies, and perspectives on the evolving landscape of photocatalytic cyclization in heterocyclic compound synthesis. This Special Issue aims to provide a comprehensive overview of the current state of the field while inspiring further advancements in this exciting and rapidly expanding area of research.

Photocatalytic synthesis of heterocycles has emerged as a versatile strategy in organic synthesis. Among various heterocycles, five membered heterocycles such as pyrroles, indoles and their derivatives have great significance based on their pharmaceutical applications. Diverse photocatalysts have shown great potential in synthesis of nitrogen heterocycles either through radical-based mechanism or via energy transfer pathway. Compared to other synthesis routes, the photocatalytic approach offers unique advantages including green synthesis, one step reaction and approaching the challenging reaction to prepare nitrogen heterocycles. Tuning redox potential or tailoring triplet state energies of photocatalysts can play crucial role in selective and efficient synthesis of nitrogen heterocycles. In this review we have briefly covered the latest developments demonstrated for photocatalytic synthesis of five membered nitrogen heterocycles including pyrroles and indoles and their derivatives. We also discuss the existing challenges, bottlenecks and the future outlook in this field, aiming to advance photocatalytic strategies of producing five membered nitrogen heterocycles as valuable tools in modern synthetic chemistry.
