A highly enantiomeric excess in an asymmetric Pummerer-type rearrangement of chiral, non-racemic sulfoxides using O-silylated ketene acetal and the first successful Pummerer-type rearrangement on aromatic rings, are described.

Silylene protection of two dihydroxy groups of the peri-hydroxy aromatic sulfides 6a-f was essential for the subsequent Pummerer-type reaction. The overall process provided a novel and efficient approach to the peri-hydroxy dihydroquinone derivatives 9a-f.
