Metathesis Reactions of Carbohydrates: Recent Highlights in Cross‐Metathesis
European Journal of Organic Chemistry, 2010AbstractMetathetical processes play a prominent role in the development of useful transformations because of their mildness, tolerance of functional groups, and synthetic potential. On the other hand, carbohydrates have gained well‐deserved relevance in the study of biological processes.

AbstractIsomerizing olefin metathesis is currently undergoing a transformation from laboratory curiosity to powerful synthetic concept at the heart of orthogonal tandem catalysis. In this process, an isomerization catalyst continuously moves double bonds along carbon chains, while a metathesis catalyst scrambles the residues at the C−C double bonds ...

AbstractAccording to popular belief, oxygen and water are the natural enemies of organometallic reactions and therefore must be excluded rigorously from the reaction vessel. This belief is founded in the case of the highly reactive nucleophilic metal alkylidene complexes that were used in early catalytic olefin metathesis.
