  Asymmetric synthesis of 2-substituted butane-1,4-diols by hydrogenation of homochiral fumaramide derivatives

  摘要：

  Diastereoselective hydrogenation of homochiral fumaramides 1 derived from (2R)-Oppolzer's sultam was observed by analysis of the H-1 NMR spectra of the succinamide mixtures with de's of 77-88%. Reduction of these succinamides using LiAlH4 gave the corresponding (2S)-butane-1,4-diols and established that addition of hydrogen takes place selectively on the re-face of 14 fumaramides 1. The stereoselectivity was confirmed by estimating the ee's from the F-19 NMR spectra of the Mosher's diesters of the diols. This methodology was applied to the synthesis of selected pyrrolidine natural products in homochiral form. (C) 2004 Elsevier Ltd. All rights reserved.
