Efficient syntheses of four derivatives G2–G5 of Gabapentin (G1) have been achieved. The structures of targeted compounds were investigated by elemental analysis, FT-IR, and 1H-NMR spectroscopic method. Crystal structures of G2 and G4 determined by single crystal X-ray diffraction method are also described. In G2 the molecules are stacked over each other in the form of layers and adjacent layers run parallel to each other. Intermolecular hydrogen bonding and van der Waals interactions are responsible for building the molecular assembly and packing of molecules in the unit. In G4, the molecules are arranged in parallel sheets formed by inter-molecular hydrogen bonds. The proposed synthetic route has high impact due to its simple reaction conditions of room temperature, water as a green solvent and short time to accomplish the reaction.
已成功合成四种加巴噻亭衍
生物G2–G5(G1)。通过元素分析、FT-IR和1H-NMR光谱法研究了目标化合物的结构。还描述了通过单晶X射线衍射法确定的G2和G4的晶体结构。在G2中,分子以层的形式相互堆叠,并且相邻的层平行排列。分子间的氢键和范德瓦尔斯相互作用负责构建分子组装和单位内分子的堆积。在G4中,分子以平行片的形式排列,由分子间氢键形成。由于反应条件简单(室温、以
水作为绿色溶剂)和反应时间短,所提议的合成路线具有很高的影响力。
