摘要 描述了从羽扇豆中分离的生物碱多花素的区域特异性溴化。溴多花素及其与琥珀酰亚胺的分子复合物已通过 IR 和 NMR 光谱以及 X 射线衍射进行了表征。已确定溶液中和固态中的构象。3-溴杂多花碱和琥珀酰亚胺分子之间的分子复合物形成是羽扇豆生物碱类中的首例。该复合物的两个分子通过分子间氢键 NH⋯N 结合在一起,从而导致生物碱氮原子构型的转化。因此,环 C 采用椅子构象,而它在 3-溴多花素中呈船形。

The steric structure of multiflorine methylation products
作者:J. Thiel、W. Wysocka、W. Boczoń
DOI:10.1007/bf00812252
日期:1995.2
Multiflorine(1) - a minor lupine alkaloid - treated by methyl lithium or methyl magnesium iodide affords 4S-4-hydroxy-4-methyl-2,3-didehydrosparteine (2) and 2S-2-methyl-4-oxosparteine (3), respectively, as the dominating products. Their steric structure, determined by H-1 and C-13 NMR techniques, points to stereospecific preferences of these reactions. The observed nucleophilic 1,2- and 1,4-additions indicate that regiospecificity of the action of MeLi or MeMgI on multiflorine is different from that of the so far known similar alkylation of other enamino ketones.
