  Synthesis of Optically Active 4-Substituted 2-Aminobutyrolactones and Homoserines by Combined Aldol/Photocyclization Reactions of Chromium Aminocarbene Complexes

  摘要：

  Aldol reactions of optically active chromium aminocarbene complexes proceeded with moderate to high diastereoselectivity. Photolysis of the aldol product gave optically active 4-substituted 2-aminobutyrolactones which could be hydrolyzed to gamma-hydroxy-alpha-amino acids. Using this procedure, (+)-bulgecenine was synthesized.
