Abstract
The absolute configuration of epi- and isoshyobunone was established as 2 and 3, respectively, on the basis of their chemical and spectral data together with base-catalyzed isomerization of shyobunone (1) affording natural isoshyobunone and the enantiomer of natural epishyobunone. In addition, conformations of the base-catalyzed isomerization products (3, 6, 8, 9, and 11) are also discussed.Keywords
