Pd-Catalyzed o-C–H functionalization of α-phenylglycine, 4-hydroxyphenylglycine and phenylalanine using picolinamide as a directing group is reported. We have developed different protocols for the arylation, alkylation, alkynylation, halogenation, alkoxylation, and acyloxylation of these amino acids. The reactions exhibit high selectivity, broad substrate scope, and compatibility with different functional
据报道,使用吡啶甲酰胺作为指导基团,Pd催化了α-苯基甘氨酸,4-羟基苯基甘氨酸和苯丙氨酸的o -C–H官能化。我们已经为这些氨基酸的芳基化,烷基化,炔基化,卤化,烷氧基化和酰氧基化开发了不同的协议。反应显示出高选择性,宽泛的底物范围以及与不同官能团的相容性(中等至高收率)。它们提供了快速有效地获取各种可以进一步修饰并在医学化学中具有广泛应用范围的基于苯基的氨基酸衍生物的途径。
