discoveries in the
field of the
chemistry and

Total Synthesis & Natural Product Synthesis
"for his outstanding
achievements in the art of
organic synthesis“ (1965)
RB Woodward
Vitamin B12Reserpine
Erythromycin
In his Cope Lecture, Woodward said it best when he acknowledged the special
challenge of chemistry compared to mathematics:
“While in mathematics, presumably one's imagination may run riot without
limit, in chemistry, one's ideas, however beautiful, logical, elegant,
imaginative they may be in their own right, are simply without value unless
they are actually applicable to the one physical environment we have- in
short, they are only good if they work! I personally very much enjoy the very
special challenge which this physical restraint on fantasy presents.”
“In chemistry, ideas have to answer to reality”
Revolutionary Method for Molecular Synthesis
"for the development of the
metathesis method in
organic synthesis“ (in 2005)
Y. Chauvin R.H. Grubbs R.R. Schrock
C=C Formation by Olefin Metathesis
C=C Formation by Olefin Metathesis
Catalytic Bond Formation: C-C & C-X Bonds
R.F. Heck E. Negishi A. Suzuki
“for palladium-catalyzed
cross couplings in organic
synthesis” (in 2010)
Molecular Machines Designed by Chemists
J.-P. Sauvage J. F. Stoddart B. L. Ferringa
“for the design and
synthesis of
molecular machines”
(in 2016)
