Ian Fleming (born 1935) is an English organic chemist, and an emeritus professor of the University of Cambridge, and an emeritus fellow of Pembroke College, Cambridge. He was the first to determine the full structure of chlorophyll (in 1967)^[1] and was involved in the development of the synthesis of cyanocobalamin by Robert Burns Woodward. He has made major contributions to the use of organosilicon compounds for stereospecific syntheses; reactions which have found application in the synthesis of natural compounds. He is also a prolific author, and has written a number of textbooks, encyclopedia chapters and influential review articles.^{[citation needed]}

Ian Fleming was born August 4, 1935, in Staffordshire and grew up in Stourbridge, Worcestershire. He received a B.A. in 1959 and a Ph.D. in 1962, both from Pembroke College, Cambridge. His post-doctoral studies were done at Harvard University with R.B. Woodward on the synthesis of vitamin B₁₂. He has made advances in the topic of stereochemistry, developing new synthetic reactions. He has also pioneered the applications of organosilicon chemistry for organic synthesis, especially for the production of chiral molecules, and synthesized the highly stable 8-cycloheptatrienylheptafulvenyl carbocation.^[2]

Prof. Fleming has an extensive list of over 200 scientific publications, including major contributions to the chemical encyclopedia "Comprehensive Organic Chemistry", and many influential review articles. He has also authored popular undergraduate textbooks on spectroscopic methods of structure determination, organic synthesis, and applications of frontier molecular orbital theory to problems in organic chemistry.
