Chapter 8 consists of two vignettes, each providing personal accounts of the development of ring‐closing metathesis (RCM) approaches to the synthesis of natural products. In Vignette 1, Vanderwal describes how the structure of echinopines A and B inspired the discovery of an allylsilane RCM/electrophilic desilylation methodology for constructing carbocyclic rings with exocyclic alkenes. The implementation...
Ring closing metathesis (RCM) has emerged as a powerful tool to construct macrocyclic ring systems. However, the product distribution of monomer and oligomers is often a problem in the formation of medium to large rings. In the course of synthetic studies on the natural product radicicol and its analogs, we have found that the reaction temperature, along with concentration, has significant impact...
