The diphenol 1 was resolved into its antipodes and their absolute configuration was established. The levorotatory isomer R ‐(−)‐ 1 was oxidized to the dienone R ‐(−)‐ 6 , which was rearranged to afford natural (−)‐multifloramine ( R ‐(−)‐ 7 ), thus establishing that the latter has the R ‐configuration. By the same reaction sequences, the enantiomeric diphenol S ‐(+)‐ 1 was transformed to provide (+)‐multifloramine ( S ‐(+)‐ 7 ) of the S ‐configuration.
