Results from studies of the Arndt–Eistert homologation of N-methyl-α-amino acids with concomitant ester and amide formation is discussed. The applicability of the use of ultrasound was investigated in the Wolff rearrangement of diazoketones for the production of esters and amides. This methodology was then applied to a novel ‘N-methyl coupling’ that allows simultaneous β-amino acid formation. Conventional ‘PyBroP N-methyl couplings’ were also performed as a comparison to establish the validity of the method.
讨论了 N-甲基-
α-氨基酸的 Arndt-Eistert 同源反应以及同时形成酯和酰胺的研究结果。研究了在重
氮酮的沃尔夫重排反应中使用超声波生成酯和酰胺的适用性。然后将此方法应用于一种新型的 "N-甲基偶联",可同时生成 β-
氨基酸。此外,还对传统的 "
PyBroP N-甲基偶联 "进行了比较,以确定该方法的有效性。
