of nucleic acid-mediated excess electron transfer, a bis-functionalized (2-aminoethyl)glycine-PNA modified with a flavin and an oxetane moiety was synthesized. The solid-phase synthesis of the required PNA oligomer was especially intriguing because of the high acid sensitivity of the oxetane moiety, so the Fmoc/Bhoc strategy was adapted to the mild cleavage conditions of the Sieberamide resin.

在研究核酸介导的过量电子转移的背景下,合成了用黄素和氧杂环丁烷部分修饰的双功能化(2-氨基乙基)甘氨酸-PNA。由于氧杂环丁烷部分的高酸敏感性,所需 PNA 低聚物的固相合成特别有趣,因此 Fmoc/Bhoc 策略适用于 Sieberamide 树脂的温和裂解条件。除了顺利的低聚条件外,还报道了氧杂环丁烷和黄素官能化的 Fmoc 保护的(2-氨基乙基)甘氨酸结构单元的合成。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
