Herein, we report a novel strategy for the synthesis of racemic α-arylglycines based on the selective arylation of DEAM with diaryliodonium salts under mild, transition metal-free conditions. The reaction features good functional

  乙酰胺丙二酸二乙酯 (DEAM) 已广泛用于在碱性条件下通过 C-烷基化然后水解/脱羧来合成 α-氨基酸。相比之下，该试剂的 C-芳基化仍未开发。在此，我们报告了一种合成外消旋 α-芳基甘氨酸的新策略，该策略基于 DEAM 与二芳基碘鎓盐在温和、无过渡金属的条件下选择性芳基化。该反应具有良好的官能团耐受性和易于扩展的特点，适用于芳烃（包括已批准的药物）的化学选择性C-H-修饰，从而能够以一种直接的方法来制备复杂的α-芳基甘氨酸，而这在其他情况下是具有挑战性的。

  Sulfuryl chloride has been used to mono-chlorinate electron-rich arylalkyl- and heteroarylalkyl-amines and amino acids in a mild and efficient one-pot transformation with straightforward purification­. Protection of the amines was not needed, and racemization of the chiral amino acids was minimal.

  The enantioselective reaction of α-substituted β-nitroacrylates with oxazol-5-(4H)-ones (oxazolones) to construct consecutive tetrasubstituted stereogenic centers was accomplished. A cinchona alkaloid sulfonamide catalyst afforded products bearing vicinal chiral centers with excellent enantio- and diastereoselectivities. The obtained products were successively converted into various chiral compounds
