3-d][1,3]benzooxazocin-13-one. X-ray crystal structure analysis of compounds 6a and 16a revealed that the cleft angles of the planes of the benzopyran moiety and the p-methoxybenzene ring are 109.4° and 108.6°, respectively. The conformation of the aromatic ring at the bridgehead of 16, 16a and 20 is restricted by the gem-dimethyl groups on the C-9 position and the methyl group on the nitrogen atom
这项工作描述了衍生自苯并吡喃 [4,3-d][1,3] benzooxazocin-13-one 的官能化裂隙分子 6、6a、16、16a、17、19 和 20 的有效合成。化合物6a和16a的X射线晶体结构分析表明,苯并吡喃部分和对甲氧基苯环的平面裂角分别为109.4°和108.6°。16、16a和20桥头芳环的构象受到环中C-9位上的勐二甲基和环中氮原子上的甲基的限制。
