building block can be used as a scaffold for the solid-phase synthesis of dipodal or cyclic peptidic receptors. It allows the preparation of tweezer receptors with unsymmetrically substituted side arms and therefore for the implementation of an enhanced structural and functional diversity in comparison to symmetric tweezers.(© Wiley-VCH Verlag GmbH & Co.

开发了一种新的多功能模板 3-(N-Boc-氨基甲基)-5-(N-Fmoc-氨基甲基) 苯甲酸 (1) 的合成并在此进行了报道。合成策略的关键特征是使用双相反应混合物选择性地单还原对称二叠氮化物。单还原允许连续引入两个正交保护基团——例如 Fmoc 和 Boc。该构建块可用作双足或环状肽受体固相合成的支架。它允许制备具有不对称取代侧臂的镊子受体,因此与对称镊子相比,可以实现增强的结构和功能多样性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
