摘要
1,3-Enynes are hardly amenable to trans-hydrometalation reactions, because they tend to bind the standard ruthenium catalysts too tightly. However, catalysts comprising a [Cp*Ru-Cl] unit allow such compounds to be used, provided they contain an OH group next to the triple bond. This aspect is illustrated by a formal synthesis of the lichenderived macrolide aspicilin. The required macrocyclic enyne precursor was formed by an efficient ring-closing alkyne metathesis reaction.
