摘要
The Ramberg-Bcklund rearrangement has been successfully utilized to convert readily available - and -hydrogen bearing substituted dibenzyl sulfones into corresponding stilbene derivatives, which is conveniently followed by hydrogenation in the presence of 10% Pd/C to afford the natural bibenzyls.
