dichroic spectra using the empirical method. The absolute configuration of 3,4-dihydrodiol of 7,9-dimethylbenz[c]acridine was determined by the exciton chirality method from the CD spectrum of its bis-4-(dimethylamino)benzoate ester. For the 8,9-dihydrodiol of 7,10-dimethylbenz[c]acridine the absolute configurations were tentatively assigned by normal-phase HPLC comparison of the (+)-HCA esters with
反相高效液相色谱分离了未经处理的苯巴比妥和3-甲基胆碱预处理的大鼠肝微粒体中与大鼠肝微粒体一起孵育形成的7,9-二甲基苯并[c] ac啶和7,10-二甲基苯并[c] ac啶的单官能化二氢二醇代谢物液相色谱。通过具有(+)-(1R,2S,4S)-endo-1,4,5,6,7,7-六氯双环-[2.2.1] hept-5的非对映异构酯的HPLC测定每种对映异构体的相对量烯-2-羧酸(HCA)。对于K区二氢二醇,使用经验方法从其圆二色光谱确定绝对构型。通过激子手性法从其双-4-(二甲基氨基)苯甲酸酯的CD光谱确定了7,9-二甲基苯并[c] ac啶的3,4-二氢二醇的绝对构型。对于8,的8,9-dihydrodiol 通过(+)-HCA酯的正相HPLC与文献数据的比较,初步确定了10-二甲基苯并[c] ac啶的绝对构型。在每种情况下,对于非K区二氢二醇,R,R-构型的光学纯度> 86%,对于K区二氢二醇,光学纯度>
