Diastereomeric cis- and trans-tetrahydro-4-aryl-3-[(dimethylamino)methyl]-2H-pyranols derived from 3-[(dimethylamino)methyl]tetrahydro-4H-pyran-4-one (5), have been prepared and their configurations were established on the basis of ir data. The biologically more potent trans isomer 3 was resolved into its optical antipodes and the absolute stereochemistry of one of the enantiomers 14, was determined by
非对映体顺式-和反式-四氢-4-芳基-3 - [(二甲基氨基)甲基] -2- ħ -pyranols从3衍生的- [(二甲基氨基)甲基]四氢-4- ħ -吡喃-4-酮(5),具有已准备好,并根据红外数据建立了它们的配置。将生物学上更有效的反式异构体3解析为其旋光对映体,并通过X射线晶体学测定对映体14之一的绝对立体化学。一些化合物显示出与可待因相当的镇痛活性。
