  Synthesis of β-Amino Acids Based on Oxidative Cleavage of Dihydropyridone Derivatives

  摘要：

  A new method for the synthesis of beta-amino acids based on 2,3-dihydropyridones as starting materials is presented. Conversions of 2,3-dihydropyridones with NalO(4) and subsequently with base gave the corresponding beta-amino acids in a one-pot procedure. The reactions have been monitored by H-1 NMR indicating that the beta-amino acids were formed in quantitative yields mostly. This method appears to be of broad scope, as 2-substituted 2,3-dihydropyridones are easily accessible via N-acyliminium ions generated from 4-methoxypyridine.
