Stereospecific synthesis of α,ω-cis- and α,ω-trans-disubstituted oxepanes

An efficient and versatile method for the stereospecific construction of α,ω-cis- and α,ω-trans-disubstituted oxepane skeletons is described. Cyclization of the hydroxy epoxides promoted by a (Bu3Sn)2O/ Zn(OTf)2 system proceeded via an S(N)2 process and exo mode selectivity regardless of the configuration of the hydroxyl and the epoxy groups to provide the corresponding oxepanes in excellent yields.
