The nobel prize in chemistry, 2005
"for the development of the metathesis method in
organic synthesis"
Considering the short time during which Grubbs
and Schrocks catalysts have been available, the
breadth of applications, is truly
remarkable. Prof. Per Ahlberg Nobel Committee

Olefin Cross Metathesis (CM) review in Handbook
of Metathesis by Chatterjee, A. K. (chapter 2.8,
Vol. 2 pp. 246-295) review covering 1998-2002
Connon, S. J. Blechert, S. Angew. Chem. Int. Ed.
2003, 42, 1900
Cross-metathesis methodologies have recently been
shown to be highly effective in the synthesis of
insect pheromones, polymer additives, and fine
chemicals, i.e., valuable synthetic intermediates
such as novel a,b-unsaturated carbonyl
systems. Pederson, R. L. in Handbook of
Metathesis Vol. 2 p 491

summary
  • Cross Metathesis increasingly used as
    disconnection late in natural product total
    synthesis
  • Useful tool for library synthesis, especially in
    biochemical-type applications
  • Ideal reaction a catalytic method for a
    highly efficient (re atom economy) C-C bond
    forming reaction
  • Improvement still possible in catalyst loading,
    stoichiometry, reaction time/temperature,
    selectivity,
