Aib-containing peptides have been synthesized from the N- to the C-terminus by the “azirine/oxazolone method” under solid-phase conditions. In this new and convenient method for the synthesis of sterically demanding peptides on solid phase, 2H-azirine-3-amines are used to introduce aminoisobutyric acid, an α,α-disubstituted α-amino acid, into the peptide without the need for further reagents.

含 Aib 的肽已在固相条件下通过“氮丙啶/恶唑酮方法”从 N 端合成到 C 端。在这种在固相上合成空间要求高的肽的新方法中,使用 2H-azirine-3-amines 将氨基异丁酸(一种 α,α-二取代的 α-氨基酸)引入肽中,而无需进一步试剂。已经通过这种方法制备了天然存在的 peptaibols 的片段。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
