The major metabolite of chloroquine, (+)-desethylchloroquine, produced by stereoselective N-dealkylation of the drug, was obtained in 81.5% enantiomeric purity by resolution of racemic desethylchloroquine using an atropisomeric resolving agent and was shown by circular dichroism to have the absolute (S)-configuration. The minor metabolite N-acetyldesethylchloroquine was prepared in both the racemic
氯喹的主要代谢物 (+)-去乙基氯喹是通过药物的立体选择性 N-脱烷基化产生的,通过使用阻转异构拆分剂拆分外消旋去乙基氯喹以 81.5% 的对映体纯度获得,并通过圆二色性显示具有绝对 ( S)-配置。次要代谢物 N-乙酰去乙基氯喹以外消旋和 (S)-(+)-形式制备。
