Prof. Roderick Bates received his PhD at Imperial College, London with Professor Steven Ley, using organoiron complexes for organic synthesis. After a postdoctoral stint at Colorado State University with Professor L. S. Hegedus working on chromium carbenes, he moved to the University of North Texas as an Assistant Professor. After some years spent in Thailand at Chulalongkorn University and the Chulabhorn Research Institute and a short stay in the ill-fated Department of Chemistry at Exeter in England, he joined Nanyang Technological University as a pioneer member of the Division of Chemistry and Biological Chemistry. He is currently an Associate Professor and a Fellow of NTU’s Teaching Excellence Academy.
He has research interests in the use of transition metals in organic synthesis, stereocontrol in natural product synthesis and drug discovery. His book “Organic Synthesis using Transition Metals” (2nd Ed.) was published by Wiley in April 2012. He is also a lecturer on Forensic Science for a Coursera MOOC.
The use of catalysis is now ubiquituous in organic synthesis. In this talk, I will discuss some recent examples of how we have used various kinds of catalysis to facilitate chemical transformations. These include acid and base catalysis, both in the Brønsted and Lewis senses, as well as transition metal catalysis. We have also extended the idea of using transition metal catalysis to the concept of bimetallic catalysis: using two quite different metal complexes to doubly active the substrate. These reactions are applied to the synthesis of natural products and unnatural products, especially in the field of alkaloids.
