A concise total synthesis of (+/-)-pisiferin has been accomplished from commercially available compounds alpha-cydocitral (9) and 4-bromo-2-isopropylphenol (10) via Suzuki coupling and F-C alkylation as key reaction in five steps with an overall yield of 22%. The feature of this concise synthesis is a convergent strategy coupled by Suzuki reaction. This work not only provides a strategy to approach the total synthesis of pisiferin itself but also serves as an additional correlation origin to which many related icetaxane-type diterpenes can be referred.
