  酰胺的α-手性中心的高对映建设通过α的铱催化加氢，β -不饱和酰胺

  摘要：

  Abstractmagnified imageThe chiral center at the α‐position of amides is installed in excellent enantioselectivity via the iridium‐catalyzed asymmetric hydrogenation of α,β‐unsaturated amides under mild conditions. Even aliphatic amides are suitable substrates. The presence of a hydrogen atom on the nitrogen of the amide is important for the enantioselectivity of the reaction.

  An asymmetric hydrogenation of α‐oxymethylcinnamic acids was developed by using chiral spiro phosphine‐oxazoline/iridium complexes as catalysts to prepare β2‐hydroxycarboxylic acids with high reactivity (TON up to 2000) and excellent enantioselectivity (up to 99.5% ee). By using this highly efficient asymmetric hydrogenation as a key step, a concise total synthesis of natural product homoisoflavone

  日期：2007.7

  The enantioselective synthesis of a Q-symmetric 2-endo,6-endo-disubstituted bispidine (3,7-diazabicyclo[3.3.1]nonane) has been accomplished for the first time. The key step was a Michael addition of the protected beta-amino ester methyl (R)-3-N-benzyl-N[(S)-1-phenylethyl]amino}-3-phenylpropionate to its alpha-methylene derivative delivering an anti,anti-configured alpha,alpha'-methylene-bridged bis(beta-amino ester) as the major diastereomer. Deprotection, reduction and cyclisation furnished (1R,2R,5R,6R)-2,6-diphenyl-3,7-bis(S)-1-phenylethyl)-3,7-diazabicyclo[3.3.1]nonane in six steps and 15% overall yield. (c) 2007 Elsevier Ltd.
