Chemical resolutions of the rigid, tricyclic 3,4,5,6-tetrahydro-2-methyl-2,6-methano-2H-1-benzoxocin-4-one (6) of biological and chiroptical interest have been performed. The configurational assignment was made by X-ray analysis and chemical correlation of its ketal (+)-9a synthesized with (2R,3R)-butane-2,3-diol. Kinetic resolution of the hydroxy derivative rac-10 by means of lipase from Pseudomonas
已进行了具有生物学和手性兴趣的刚性三环3,4,5,6-四氢-2-甲基-2,6-甲氨基-2 H -1-苯并氧辛-4-酮(6)的化学拆分。通过X射线分析和与(2 R,3 R)-丁烷-2,3-二醇合成的缩酮(+)- 9a的化学相关性进行构型分配。通过洋葱假单胞菌(Pseudomonas cepacia)的脂肪酶对羟基衍生物rac - 10进行动力学拆分,证明是最有效的拆分方法。通过与缩酮(+)- 9的化学相关性推论出反应更快的对映异构体(+)- 10的立体化学。还制备了用于色丙烷发色团的手性研究的模型化合物(+)- 1和(-)- 1。
