  New synthetic approach to mevalonate and mevaldate fluoroanalogues

  摘要：

  6,6,6-Tri- and 6,6-difluoromevalonate were synthesized by new method starting from the corresponding beta-alkoxyvinyl polyfluromethyl ketones. Enantiomers of fluoromevalonates were obtained by column chromatography separation of diastereomeric (S)-(-)-1-phenylethylamides of fluoromevalonates with the following hydrolysis. Racemic 6,6,6-tri- and 6,6-difluoromevaldates were also prepared. (c) 2007 Elsevier Ltd. All rights reserved.
