Pyran derivativesR 0340 Two-Directional Olefinic-Ester Ring-Closing Metathesis Using Reduced Ti Alkyl-
idenes. A Rapid Entry into Polycyclic Ether Skeletons. — The reaction is achieved with readily available dienyl diesters in the presence of a reduced titanium ethylidene reagent and allows the rapid construction of tri-, penta-, and heptacyclic skeletons. These products, substructures of natural polycyclic ethers, are interesting tools in the study of ion channels. — (ZHANG, Y.; RAINIER*, J. D.; Org. Lett. 11 (2009) 1, 237-239; Dep. Chem., Univ.
