Synthesis of intermediate (VII): The condensation of epoxide (I) with vinyl lithium (II) by means of CuCN gives the allylic alcohol (III), which is epoxidated to epoxide (IV). The silylation of (IV) with TBDPSCl and imidazole yields the silyl ether (V), which is condensed with 1,3-dithiane (VI) by means of n-BuLi and protected with TBDPSCl as before to afford the desired intermediate (VII).
