A new approach for the stereoselective synthesis of (2R,3S)-2-amino-3,4-dihydroxybutyric acid, an α-amino acid from Lyophyllum ulmarium, has been accomplished using an ether directed aza-Claisen rearrangement. On investigation of optimal conditions for this key step it was shown for the first time that Au(I) can be used to catalyse this transformation.
立体定向合成(2 R,3 S)-2-氨基-3,4-二羟基丁酸(一种来自Lyophyllum ulmarium的α-氨基酸)的立体选择性合成新方法已经通过使用醚导向的氮杂-克莱森重排法完成。在研究此关键步骤的最佳条件时,首次证明可以使用Au(I)催化这种转化。
