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.
Highly Diastereoselective Katsuki−Jacobsen Oxidation−Epoxidation of α-Silyloxy Sulfinyl Dienes: Synthetic Applications
摘要:
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.
