Abstract
Two asymmetric syntheses of the isostegane derivative (+)-7 are report ed, both involving oxidation of a homochiral 2,3-dibenzylbutyrolactone with phenyliodonium bis(trifluoroacetate). Of particular interest is the fact that the oxidative cyclisation leading to the biaryl link can be carried out directly on a precursor containing a hemiacetal functi onal group.
