Special Issue Information

Dear Colleagues,

The synthetic applications based on metathesis processes have recieved a huge attention over the past years. It has been an exciting adventure that will continue in the future based on the improvement in catalyst activity, tolerance and selectivity. New commercial and academic applications can be envisioned and the number of total synthesis of natural products based on these methodologies increases more and more. Ring closing metathesis (RCM) is an atom-economical reaction, compatible with many functional groups and allows the constuction of rings of practically any size including macrocycles. This special issue of Molecules will include new exciting contributions in RCM chemistry.

Abstract
Medium sized carbocycles are particularly difficult to synthesize. Ring closing metathesis reactions (RCM) have recently been applied to construct eight-membered carbocycles, but trisubstituted double bonds in the eight-membered rings are more difficult to produce using RCM reactions. In this review, model examples and [...] Read more.
Medium sized carbocycles are particularly difficult to synthesize. Ring closing metathesis reactions (RCM) have recently been applied to construct eight-membered carbocycles, but trisubstituted double bonds in the eight-membered rings are more difficult to produce using RCM reactions. In this review, model examples and our own results are cited and the importance of the preparation of suitably designed precursors is discussed. Examples of RCM reactions used in the total synthesis of natural products are also outlined. Full article
