From Conventional to Sustainable Catalytic Approaches for Heterocycles Synthesis

Synthesis of heterocyclic compounds is fundamental for all the research area in chemistry, from drug synthesis to material science. In this framework, catalysed synthetic methods are of great interest to effective reach such important building blocks. In this review, we will report on some selected examples from the last five years, of the major improvement in the field, focusing on the most important conventional catalytic systems, such as transition metals, organocatalysts, to more sustainable ones such as photocatalysts, iodine-catalysed reaction, electrochemical reactions and green innovative methods.Catalysed synthetic methods, such as transition metals, organocatalysts, photocatalysts, iodine-catalysed reaction, electrochemical reactions and green innovative methods are of great interest for the sustainable synthesis of heterocyclic compounds, important building blocks for several applications.image
