The assignments of the proton and carbon signals and conformations of substituted 2‐aryl‐trans‐decahydroquinolin‐4‐ones were determined using a combination of 1H, 13C, COSY and HETCOR spectral data. Analysis of the spectral data reveals that these compounds exist predominantly in twin‐chair conformations with the aryl and alkyl substituents in the equatorial orientation. Introduction of an alkyl group
使用 1H、13C、COZY 和 HETCOR 光谱数据的组合确定了质子和碳信号的分配以及取代的 2-芳基-反式-十氢喹啉-4-酮的构象。光谱数据分析表明,这些化合物主要以双椅构象存在,芳基和烷基取代基在赤道方向。在 C-3 处引入烷基会导致 C-2-C-3 键周围的环变平。根据质子-质子耦合常数 (J9,10),发现环之间的连接是反式的。
