A systematic study on the directed Pd-catalyzed (hetero)arylation of 26 substituted cyclic α-amino acids at the C(3)-atom was performed. For the first time, the 7- and 8-membered cyclic amino acids were introduced to C–H activation. 8-Aminoquinoline was used as a directing group. Effects of the ring size and the substituents on the reaction efficacy and stereoselectivity were studied.
对C(3)原子上26个取代的环状
α-氨基酸进行定向Pd催化(杂)芳基化的系统研究。首次将7元和8元环状
氨基酸引入C–H激活。
8-氨基喹啉用作指导基团。研究了环大小和取代基对反应效率和立体选择性的影响。
