peptides. Due to the nonavailability of simple synthetic methods to deliver complex cyclic AAAs, only simplest members of this class have been used in the peptide area. In this regard, we have developed a new method to prepare various highly functionalized tetralin-based unusual AAA derivatives 22, 37-43 by trapping o-xylylene (or o-quino-dimethane) intermediate with methyl 2-acetamidoacrylate (12). In addition
基于 Tetralin 的 α-氨基酸 (AAA) 是苯丙氨酸 (Phe) 的受限类似物,广泛用于各种生物活性肽的设计和合成。由于无法使用简单的合成方法来传递复杂的环状 AAA,因此在肽领域仅使用了此类中最简单的成员。在这方面,我们开发了一种新方法,通过用 2-乙酰氨基丙烯酸甲酯 (12) 捕获邻二甲苯(或邻醌二甲烷)中间体来制备各种高度官能化的基于四氢化萘的不寻常 AAA 衍生物 22、37-43。此外,我们还通过 Suzuki-Miyaura 交叉偶联反应对 diidotetralin 衍生物 40 进行了修饰。
