Article abstract of DOI:10.1246/cl.1985.1153

A new reductive 1,2-rearrangement of aryl (or alkenyl) groups of α-sulfonyloxy acetals to give the title compounds was developed by using the combination of i-Bu2AlH and Et3Al, and this method was applied to the synthesis of optically pure (R)-(-)-α-curcu
