steps constitute the totalsynthesis of (+)‐dactylolide: the 1,6‐oxa conjugate addition reaction of a 2,4‐dienal for the facile synthesis of the 2,6‐cis‐2‐(4‐oxo‐2‐butenyl)tetrahydropyran subunit, the umpolung alkylation reaction of a cyanohydrin, and the NHC‐catalyzedoxidativemacrolactonization reaction for the synthesis of the 20‐membered macrocyle. NHC=N‐heterocyclic carbene.
