Abstract An enantioselective total synthesis of the lindenane sesquiterpene (+)- sarcandralactone A has been accomplished for the first time. The synthesis features a SeO 2- mediated [2, 3]-sigmatropic rearrangement for the facile construction of the tertiary allylic alcohol as a single diastereoisomer.
