Full Description
Photocatalytic routes to heterocycles with detailed mechanistic and sustainability coverage
Photocatalytic Synthesis of Heterocyclic Compounds connects traditional and photocatalytic approaches to heterocycle formation, addressing the demand for greener synthetic methodologies in pharmaceuticals, agrochemicals, and materials science.
This book covers photophysical and photochemical fundamentals underlying photoredox catalysis, it then examines radical and ionic pathways using both metal-based and metal-free catalysts. Synthetic coverage spans five-membered, six-membered, and fused heterocyclic systems. Methodologies emphasizing atom economy, reduced energy consumption, and minimal environmental impact are presented alongside discussion of current challenges and future directions in the field.
Key topics include:
Mechanistic analysis of photoredox catalytic cycles relevant to nitrogen-, oxygen-, and sulfur-containing heterocycle formation under visible light conditions
Comparative evaluation of metal-based and metal-free photocatalyst systems for efficient heterocyclic ring construction via radical and ionic pathways
Green chemistry methodologies prioritizing atom economy, reduced energy input, and minimized waste generation in heterocycle synthesis
Applications of photocatalytic-synthesized heterocycles in pharmaceutical development, agrochemical design, and advanced materials science
Assessment of current limitations and future research directions for scaling photocatalytic heterocycle synthesis toward practical implementation
Synthetic organic chemists, medicinal chemists, and materials scientists seeking sustainable routes to heterocyclic scaffolds will find this volume a valuable resource. By consolidating photocatalytic strategies across heterocycle classes, it serves researchers and industry professionals advancing green chemistry in heterocyclic compound production.
