The first total synthesis of two natural 6-C-prenylflavanones, (±)-6-C-prenyleriodoctyol (1) and 6-C-prenylnaringenin (2), using the acetophenone derivative 6 as the key intermediate is described. This new efficient synthetic approach was mainly based on Claisen rearrangement and cyclization reaction.
