摘要:
The Ramberg-Backlund rearrangement has been successfully utilized to convert readily available α-and α'-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.
