 Hello everyone, I am Professor Krishna Kaliapan from IIT Bombay. I shall be delivering a course on Classics in Total Synthesis. This is actually part one of this series and here I will talk about Total Synthesis of many natural products in this course. The contents are, as you know, Total Synthesis is a very important topic in organic chemistry. Early 20th century, Total Synthesis was used to confirm the structure of natural product isolated from nature. Later, whenever a new reagent, new catalyst, new reactions were discovered, the versatility of that were tested on Total Synthesis of natural products. So, what we will do in this course is to discuss Total Synthesis of many natural products about 75 to 80 Total Synthesis we will try to cover in this course and who all can attend this course. As this course is slightly on the advanced level, MSC and PhD students will get maximum benefit by attending this course. And those who are already exposed to various organic reactions, rearrangements and initial introduction to Retro Synthesis can attend this course and they will be benefited. And what will they gain by attending this course? As I mentioned, we will talk about 75 Total Synthesis and each Total Synthesis will have at least 2 to 3 key reactions. That means you will get an opportunity to learn about 200 key reactions which are used in the Total Synthesis of natural products and how they use these key reactions in Total Synthesis of many natural products and also you will learn many strategies used in Total Synthesis of natural products. So, looking forward to discussing classics in Total Synthesis with all of you in the forthcoming semester. Thank you.
