Synthesis, spectral and structural characterization of a pyrroloindolizine derivative having structural similarity with calix[2]pyrrole is described. Here, two pyrrole rings are connected with two meso-carbon atoms having an N,α-linkage and an α,β-linkage to afford the smallest analogue in the calixpyrrole family. Detailed NMR spectroscopic studies along with single crystal X-ray analysis confirm the assigned structure of the molecule.
本文描述了一种与 calix[2]pyrrole 结构相似的吡咯吲嗪衍生物的合成、光谱和结构特征。在这种衍生物中,两个吡咯环与两个具有 N,α-连接和 α,β-连接的中碳原子相连,从而产生了卡利克吡咯家族中最小的类似物。详细的核磁共振光谱研究和单晶 X 射线分析证实了该分子的指定结构。
