Although initial examples of ring-closing metathesis used poorly defined metal catalysts, subsequent development of Schrock-type molybdenum catalysts such as 1 and Grubbs-type ruthenium catalysts such as 2 - 6 greatly expanded the scope and utility of RCM (Eq. 2). In general, molybdenum catalysts display high activity but are unstable toward air or water; ruthenium catalysts are less active but exhibit good selectivity and functional-group compatibility. RCM has been employed extensively in organic synthesis to establish both saturated and unsaturated rings; the reaction can be used to form carbocycles or heterocycles.
Ruthenium-based olefin metathesis catalysts bearing carbohydrate-containing N-heterocyclic carbenes were synthesized and their structural characteristics analyzed. The catalysts showed good to excellent activity in a variety of metathesis reactions, including ring-closing metathesis, ring-opening metathesis polymerization, cross-metathesis, and asymmetric ring-opening cross-metathesis.

For metathesis, the 00’s was the decade of the second generation ruthenium catalysts. Besides the well-known 2nd generation Grubbs and Hoveyda-Grubbs catalysts, hundreds of catalysts featuring heterocyclic carbene ligands have been published in the past ten years. There are actually so many that it has become nearly impossible to have a clear idea of what has been tried or done. Fortunately, two very complete and up-to-date reviews recently published by Grela and Grubbs help us keep track of everything!
