Euryfuran synthesis

Methoxy(phenylthio)methane and methoxy(phenylsulfonyl)methane are useful fonnyl anion equivalents for one-carbon homologation. For instance, addition of methoxy(phenylthio)methyllithium to ketones, followed by rearrangement of the adduct, provides a new method for the preparation of a-(phe-nylthio) aldehydes (equation 39). The rearrangement is stereospecific. This meAod has been used for the total synthesis of annelated furans such as (+)-euryfuran, butenolides such as isoderminin and con-fertifolin and spirocyclic tetrahydrofiirans and butenolides. ... [Pg.570]
