From bergamot oil ( Citrus bergamia RISSO), (−)‐(4 S , 8 R )‐8‐epi‐α‐bisabolol ( 2 ) and (−)‐(4 R , 8 S )‐4‐epi‐β‐bisabolol ( 3 ) were isolated. The absolute configuration of their stereoisomers 4 and 5 was established by an enantioselective synthesis starting from (−)‐( S )‐ p ‐mentha‐1,8‐dien‐4‐ol.
