Construction of Building-Blocks for Polyether Synthesis Using Sequential CataRing-Closing Enyne and Cross Metathesis. — Highly functionalized six- and
15- 126 lytic
seven-membered cyclic ethers bearing a variety of side chains are synthesized using
ring-closing enyne metathesis and subsequent cross metathesis of the intermediate
diene. One-pot enyne and cross metathesis is accomplished, allowing ring construction
and side chain introduction to be performed in a single operation. — (CLARK*, J. S.;
