The samarium(II)-mediated intermolecular couplings of ketones and β-alkoxyacrylates: a short asymmetric synthesis of an antifungal γ-butyrolactone
摘要:
The samarium(II) iodide-mediated coupling of ketones with beta-alkoxyacrylatcs gives beta-hydroxy-gamma-butyrolactones in moderate yield. The process has been applied to the asymmetric synthesis of an antifungal, gamma-butyrolactone natural product. (C) 2004 Elsevier Ltd. All rights reserved.
