title: Highly diastereoselective Katsuki-Jacobsen oxidation-epoxidation of alpha-silyloxy sulfinyl dienes: synthetic applications.
abstract: Katsuki-Jacobsen oxidation-epoxidation of acyclic alpha-silyloxy sulfinyl dienes, followed by acid-promoted cyclization, leads to 2,5-trans-sulfonyl dihydrofurans with good selectivities. As an application, the formal syntheses of (6S,7S,9R,10R)- and (6S,7S,9S,10S)-6,9-epoxynonadec-18-ene-7,10-diols is reported.
