Palladium-catalyzed intramolecular aryl etherification reaction using bulky binaphthylphosphane ligand is shown to be a convenient method for the synthesis of seven-membered heterocycles. Application of this methodology to a naturally occurring proteinogenic l-amino acid has led to the synthesis of optically active benzoxazepine ring systems of versatile biological importance. amino acids - palladium
使用大体积的联萘膦配体进行钯催化的分子内芳基醚化反应是合成七元杂环的便捷方法。将该方法应用于天然存在的蛋白质生成的1-氨基酸已经导致了具有多种生物学重要性的旋光性苯并ze氮平环系统的合成。 氨基酸-钯-配体-醚化-手性苯并x氮平
