The conformational analyses of 9, 10-dihydroanthracene and several of its methylated and ethylated derivatives are studied by empirical force field calculations (MM2 and MMPI). The computational results are considered in light of previous and current carbon NMR data. Model compounds are examined which involve fixed, planar, and boat-shaped conformations about the central ring, and these /sup 13/C NMR
通过经验力场计算(MM2 和 MMPI)研究了 9, 10-二氢蒽及其几种甲基化和乙基化衍生物的构象分析。根据以前和当前的碳 NMR 数据考虑计算结果。检查模型化合物,其中涉及围绕中心环的固定、平面和船形构象,然后将这些 /sup 13/C NMR 数据与灵活系统进行比较。得出的结论是,碳化学位移和碳氢耦合常数与分子力学计算的结果一致,这表明中心环周围的平面性比以前认为的更大。
