Abstract: | A C1–C6 fragment of pinnatoxin A, (5S,6R)-5,6-dimethyl-3-methyleneoxepan-2-one, which features a γ,δ-trans-dimethylsubstituted α-methylene lactone, has been synthesized in an optically pure form from ethyl (E)-4-benzyloxy-2-butenoate through an auxiliary-based conjugate addition and alkylation reaction. The excellent diastereoselectivity (98:2) observed in the alkylation reaction would be a result of stereocontrol from both the adjacent stereocenter and the chiral oxazolidinone. |
