A variety of triflates containing a β-oxygen functionality were efficiently reacted with Grignard reagents in the presence of CuBr to afford the corresponding coupling products.

A general synthetic strategy for constructing seven- and eight-membered cyclic ether derivatives is described.The important feature of this work is a highly stereoselective reduction of bicyclic ketals, i.e., cis-selective reduction with triethylsilane/TiCl4 and trans-selective reduction with diisobutylaluminum hydride (DIBAL).The procedure completed a new and efficient synthesis of isolaurepinnacin and lauthisan skeletons in optically active forms.
