burgeoning interest of the pharmaceutical industry in α-amino acid derivatives, discovering strategies for the synthesis of allylic azlactones is important. Herein, we establish a transition-metal-free regioselectivity switch of α-amino acid-derived esters and MBH carbonates, which exhibits broad reaction scope and good reaction yields. Control reactions indicate that both base and solvent are important
烯丙基吖内酯在潜在的生物活性和合成应用方面具有非常重要的意义。由于制药工业对α-氨基酸衍生物的兴趣日益浓厚,发现烯丙基吖内酯的合成策略非常重要。在此,我们建立了α-氨基酸衍生的酯和MBH碳酸酯的无过渡金属区域选择性开关,其表现出广泛的反应范围和良好的反应产率。对照反应表明碱和溶剂对于区域选择性都很重要。
