  Quinazoline skeletons are synthesized by amino acid catabolism/reconstruction combined with the insertion/cyclization of dimethyl sulfoxide for the first time. The amino acid acts as a carbon and nitrogen source through HI-mediated catabolism and is then reconstructed using aromatic amines and dimethyl sulfoxide (DMSO) as a one-carbon synthon. This protocol is of great significance for the further

  喹唑啉骨架是首次通过氨基酸分解代谢/重建结合二甲基亚砜的插入/环化合成。氨基酸通过 HI 介导的分解代谢充当碳和氮源，然后使用芳香胺和二甲基亚砜 (DMSO) 作为单碳合成子进行重建。该方案对进一步研究氨基酸转化具有重要意义。
• Synthesis of Unprotected 2-Arylglycines by Transamination of Arylglyoxylic Acids with 2-(2-Chlorophenyl)glycine

  日期：2020.9.4

  The transamination of α-keto acids with 2-phenylglycine is an effective methodology for directly synthesizing unprotected α-amino acids. However, the synthesis of 2-arylglycines by transamination is problematic because the corresponding products, 2-arylglycines, transaminate the starting arylglyoxylic acids. Herein, we demonstrate the use of commercially available l-2-(2-chlorophenyl)glycine as the

  用2-苯基甘氨酸对α-酮酸进行氨基转移是直接合成未保护的α-氨基酸的有效方法。但是，通过氨基转移合成2-芳基甘氨酸是有问题的，因为相应的产物2-芳基甘氨酸使起始的芳基乙醛酸发生氨基转移。在此，我们展示了使用可商购获得的升-2-（2-氯苯基）甘氨酸作为在arylglyoxylic酸氨基转移氮源，在不脱离不希望的自转移方法干扰产生相应的2-芳基甘氨酸。
