An efficient palladium-catalyzed ortho-alkoxylation of N-benzoyl α-amino acid derivatives at room temperature has been explored. This novel transformation, using amino acids as directing groups, Pd(OAc)2 as catalyst, alcohols as the alkoxylation reagents, and PhI(OAc)2 as the oxidant, showed wide generality, good functional tolerance, and high monoselectivity and regioselectivity.
已经探索了在室温下钯的有效催化N-苯甲酰基α-氨基酸衍生物的邻烷氧基化。这种新颖的转化,以氨基酸为导向基团,以Pd(OAc)2为催化剂,以醇为烷氧基化试剂,以PhI(OAc)2为氧化剂,显示出广泛的通用性,良好的功能耐受性以及高单选择性和区域选择性。
