Stereocontrolled Total Syntheses of (−)‐Rotenone and (−)‐Dalpanol by 1,2‐Rearrangement and SNAr Oxycyclizations

Stereocontrolled Total Syntheses of (−)‐Rotenone and (−)‐Dalpanol by 1,2‐Rearrangement and SNAr Oxycyclizations: The total syntheses of (−)‐rotenone and (−)‐dalpanol have been achieved by a group‐selective, stereospecific 1,2‐shift of an epoxy alcohol and SNAr cyclizations. Three oxacycles are constructed, thus illustrating...
