Oxocarbenium Ion Mediated Alkylation and Ring-Closing Metathesis: A General Iterative Approach towards Synthesis of Linearly Fused cis:anti:cis Polycyclic Ethers
A general stereoselective method for the synthesis of cis:anti:cis polycyclic ethers containing six-, seven-, and eight-membered rings from a simple precursor has been reported. The methodology involves oxonium ion mediated intramolecular cyclization, carbon-carbon bond formation and ring-closing metathesis as key features.
