A thiocarbonyl ylide generated by sila-Pummerer rearrangement of bis(trimethylsilylmethyl) sulfoxide reacted with C6o to give a tetrahydrothiophene-fused C6o derivative. The cycloadduct was readily oxidized with mCPBA to give the corresponding sulfoxide and sulfone derivatives, which are useful for
