techniques were used to distinguish the methyl, methylene and methine carbon resonance signals of calix[4]arene 1. Correlation of 1D (1H, 13C1H}, DEPT) and 2D (HMQC and HMBC) NMR data was used to completely assign various overlapping and broad signals of calix[4]arene 1. Heteronuclear multibond correlation (HMBC) studies were used to completely assign various carbon resonances. Our results show that the conformation
新的杯[4]芳烃基四酮的1 H和13 C NMR光谱通过一维和二维同核和异核实验(1 H– 1 H COSY,1 H– 13 C HMQC和HMBC)分别在25°C标准脉冲序列的400和100 MHz下工作。在室温下测量25,26,27,28-四甲基杯[4]芳烃四酮(1)的1 H和13 C光谱。13 C 1 H},DEPT和NMR技术用于区分杯[4]芳烃1的甲基,亚甲基和次甲基碳共振信号。一维相关(1 H,13 C 1 H},DEPT)和2D(HMQC和HMBC)NMR数据用于完全分配杯[4] arene 1的各种重叠信号和宽信号。异核多键相关性(HMBC)研究用于完全分配各种碳共振。我们的结果表明,杯中的杯[4]芳烃1的构象与文献报道的视锥构象非常相似。
