Ruthenium Promoted On-DNA Ring-Closing Metathesis and Cross-Metathesis
Bioconjugate Chemistry, 2017DNA-encoded library technology (ELT) is now widely used in pharmaceutical, biotechnological, and academic research for hit identification and target validation. New on-DNA reactions are keys to exploring greater chemical space and accessing challenging chemotypes such as configurationally constrained macrocycles.

Cross‐Metathesis of Terminal Alkynes
Chemistry – A European Journal, 2014AbstractTerminal acetylenes are amongst the most problematic substrates for alkyne metathesis because they tend to undergo rapid polymerization on contact with a metal alkylidyne. The molybdenum complex 3 endowed with triphenylsilanolate ligands, however, is capable of inducing surprisingly effective cross‐metathesis reactions of terminal alkyl ...

Catalytic Alkane Metathesis by Tandem Alkane Dehydrogenation-Olefin Metathesis
Science, 2006With petroleum supplies dwindling, there is increasing interest in selective methods for transforming other carbon feedstocks into hydrocarbons suitable for transportation fuel. We report the development of highly productive, well-defined, tandem catalytic systems for the metathesis of n -alkanes.

Tandem dienyne cross-metathesis/ring-closing metathesis
Tetrahedron Letters, 2001Abstract Tandem enyne cross-metathesis/ring-closing metathesis between terminal alkynes and 1,5-hexadiene has been demonstrated using the 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene-substituted ruthenium benzylidene complex. Synthesis of 2-substituted 1,3-cyclohexadienes using this one step tandem reaction is reported.

Chemical Communications, 2011
This short account discusses the awesome power of metathesis which has profoundly changed the practice of natural product synthesis during the last decade. Since a comprehensive coverage is beyond the scope of this highlight article, I shall focus on the conceptual framework and on significant advances since the turn of the century.
