The absolute configuration of the stereogenic carbinolcenters in nine annonaceous acetogenins has been determined by careful 1 H- and 19 F-NMR analysis of (S)- and (R)-Mosher ester [methoxy(trifluoromethyl)phenylacetate or MTPA] derivatives. These acetogenins include five adjacent bis-tetrahydrofuran acetogenins [uvaricin (3), bullatacin (4), bullatacinone (5), asimicin (6), and rolliniastatin 1 (7)]
