Green Synthetic Approaches for Biologically Relevant Heterocycles

Dr. Goutam Brahmachari is a full professor of organic chemistry at Visva-Bharati University, Santiniketan, India. His research focuses on developing practical synthetic methods for carbon–carbon and carbon–heteroatom bonds using C–H functionalization, cascade, and cross-coupling techniques, with applications in medicinal heterocyclic scaffolds. He has also studied the chemistry and biology of traditionally used Indian medicinal plants, identifying novel phytochemicals of interest.He is the founding Series Editor of Elsevier’s Natural Product Drug Discovery book series and an elected fellow of the Royal Society of Chemistry. His awards include the Acharya P. C. Ray Memorial Lecture Award (2025) from the Indian Science News Association (ISNA), Kolkata, India; the Dr. Satyajit Chakraborti Memorial Award (2025) from IEM, Kolkata, India; the Chemical Research Society of India Bronze Medal (2021); the Dr. Basudev Banerjee Memorial Award (2021) from the Indian Chemical Society; the Indian National Science Academy Teachers Award (2019); the Dr. Kalam Best Teaching Faculty Award (2017); and the Academic Brilliance Award (2015).
