pyrrole-based amino acids have been prepared through the microwave assisted Paal–Knorr reaction of 1–4 ketoesters derived from the corresponding β-ketoester with a functional homologation. The carboxylic group is located in position 3 of the pyrrole, whereas the amino group, protected with the Cbz moiety, is present on the side chain in positions 1 or 2. These compounds were used to prepare constrained oligopeptides
通过微波辅助Paal-Knorr反应衍生自具有功能同源性的相应β-酮酸酯的1-4个酮酸酯,已经制备了一个新的基于吡咯的氨基酸家族。羧基位于吡咯的3位,而受Cbz部分保护的氨基位于1或2位的侧链上。这些化合物用于制备受限的寡肽。
