3-hydroxyprolines and various other amino esters are conveniently prepared by [RuCl2(p-cymene)]2-catalyzed one-pot intramolecular and intermolecular carbenoid N-H insertionreactions, respectively, and the prolines are formed with high diastereoselectivities. The catalytic reactions are tolerant toward air/moisture, and the product yields are insensitive to the organic solvents used.

This work emphasizes easy access to α-vinyl and aryl amino acids via Ni-catalyzed cross-electrophile coupling of bench-stable N-carbonyl-protected α-pivaloyloxy glycine with vinyl/aryl halides and triflates. The protocol permits the synthesis of α-amino acids bearing hindered branched vinyl groups, which remains a challenge using the current methods. On the basis of experimental and DFT studies, simultaneous
这项工作强调通过Ni 催化的工作台稳定的N-羰基保护的 α-新戊酰氧基甘氨酸与乙烯基/芳基卤化物和三氟甲磺酸酯的交叉亲电偶联,轻松获得 α-乙烯基和芳基氨基酸。该协议允许合成带有受阻支链乙烯基的 α-氨基酸,这仍然是使用当前方法的挑战。在实验和 DFT 研究的基础上,可能会同时向 Ni(0) 和 Ar-Ni( II )添加甘氨酸 α-碳 (Gly) 自由基,前者在氧化添加 C(sp 2 ) 时更受青睐) 生成的 Gly-Ni( I ) 中间体的亲电体得到关键的 Gly-Ni( III )-Ar 中间体。辅助螯合Ni 中心的N-羰基氧似乎对稳定 Gly-Ni( I ) 中间体至关重要。
