Katsuki–Jacobsen oxidation–epoxidation of α-silyloxy sulfinyl dienes: application to the formal synthesis of (6S,7S,9R,10R)-6,9-epoxynonadec-18-ene-7,10-diol
摘要:
The Katsuki-Jacobsen oxidation-epoxidation of acyclic u-silyloxy sulfinyl dienes, followed by acid-promoted cyclization, leads to 2,5-trans sulfonyl dihydrofurans with good selectivities. As an application, the formal synthesis of (6S,7S,9R,10R)-6,9epoxynonadec-18-ene-7,10-diol is reported. (c) 2007 Elsevier Ltd. All rights reserved.

stereocontrolled functionalization of conjugated sulfinyl dienes in a cascade process that involves a Michael-type addition, isomerization of a double bond and a [2,3]-sigmatropic rearrangement is reported. Enantioenriched 1,4-diol and 1,4-aminoalcohol derivatives are obtained in a very straightforward manner. Further functionalization of these structures, including highly stereoselective epoxidation,

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.

densely functionalized epoxy sulfinyl tetrahydrofurans, based on the unexpected and highlystereoselective remote nucleophilic epoxidation of hydroxy 1-sulfinyl butadienes with t-BuOOK, followed by ringclosure and subsequent epoxidation of the resulting sulfinyl dihydrofurans, is described. Alternatively, the treatment of these dienes with m-CPBA followed by acid-catalyzed cyclization gives rise to related
