(+)-(β-去氢枞酰氧基)乙基三甲基溴化铵的核磁共振谱解析

EXPLAIN FOR THE 1H - NMR AND H- H COSY OF( + ) - ( β - DEHYDROARBIEL) ETHYLTRIMETHYLAMMONIOUM BROMIDE

( + ) -(β -去氢枞酰氧基 )乙基三甲基溴化铵的1 H -NMR和H -HCOSY谱显示 ,分子的A环以椅式存在 ,而B环则以稳定的扭船式存在 。

H-NMR peaks of (+)-(β-Dehydroarbiel)ethyltrimethylammonioum Bromide were all distinguished by explaining its 1H-NMR and H-H COSY spectra,and its conformation was deducted.In the title compound,cycle A is in chair,cycle B is in twist boat,and the molecul is winding in space.
