    First asymmetric total synthesis of tupichilignan A using donor‐acceptor cyclopropanes: a structural revision of tupichilignan A.[Reference: WebLink]

    METHODS AND RESULTS:
    The first asymmetric total synthesis of Tupichilignan A was achieved using enantioenriched donor-acceptor cyclopropanes. The key steps include an asymmetric cyclopropanation using the Hayashi-Jørgensen catalyst, an oxy-homo-Michael reaction of a bicyclic D-A cyclopropane, an α-benzylation of a γ-lactone, a decarboxylation to furnish a trans-α,β−dibenzyl-γ-lactone, a configurational inversion of a hydroxy chiral center via oxidation, and a final reduction, all of which occur with high stereoselectivity.
    CONCLUSIONS:
    The spectral data of the diastereomer previously identified in the literature as Tupichilignan A were found to be inconsistent with the reported data for the natural product. On the basis of the spectral data of both synthesized diastereomers, the structure of Tupichilignan A was revised and the absolute configuration of the 7-position of Tupichilignan A was changed from R to S.
