    A New Oxyma Derivative for Nonracemizable Amide-Forming Reactions in Water
    摘要:
    An Oxyma derivative, (2,2-dimethyl-1,3-dioxolan-4-yl)methyl 2-cyano-2-(hydroxyimino)acetate (2), displayed remarkable physicochemical properties as a peptide-coupling additive for peptide-forming reactions in water. Short peptides to oligopeptides could be synthesized by using 2, EDCI, and NaHCO3 in water without measurable racemization. Significantly, a simple basic and acidic aqueous workup procedure can remove all reagents utilized in the reactions to afford only coupling products in consistently excellent yields.

    aprotic solvents and is an effective coupling reagent for N‐acyl‐protected α‐amino acids and oligo peptide segments. The conditions reported here is also effective in lactam‐forming reactions. Unlike most of the reported coupling reagents, simple aqueous work‐up procedures can remove the reagents and by‐products generated in the reactions.

    甘油丙酮醛-氧[[(2,2-二甲基-1,3-二氧杂戊-4-基)甲基2-氰基-2-(羟基亚氨基)乙酸酯(1)]显示出显着的理化性质,作为肽形成反应的添加剂。尽管已经在水或DMF介质中对具有EDCI,1和NaHCO 3的N氨基甲酸酯保护的α氨基酸建立了无消旋的酰胺形成反应,但N酰基保护的α氨基的酰胺形成了反应。酸和寡肽的片段偶联仍需要进一步开发。二乙基磷酰基-甘油丙酮酸-氧化酶(DPGOx 3)在非质子传递溶剂中表现出相对的稳定性,是一种有效的偶联剂,可用于N酰基保护的α氨基酸和寡肽片段。此处报道的条件在形成内酰胺的反应中也有效。与大多数报道的偶合试剂不同,简单的水溶液后处理程序可以除去反应中产生的试剂和副产物。版权所有©2016欧洲多肽协会和John Wiley&Sons,Ltd.
