The potential of the methyl derivative 1b as a chiral building block has been examined following the demonstrated usefulness of the compounds 1a and ent ‐ 1a. . 1b is equipped with the correct sense of chirality and the necessary functionality for stereoselective expansion of the three‐membered ring and condensation of the seven‐membered ring to give ( + )‐confertin 2 . The total synthesis of 2 is the first of an enantiomerically pure pseudoguaianolide.
