(3) has been synthesized from an optically resolved (+)-8-oxo-13-carboxytetrahydroprotoberberine (13) whose absolute configuration was established by correlation with (+)-18. This determines the absolute configurations of (+)-thalictrifoline (3) as 13R, 14R aria (+)-corydalic acid methyl ester (9) as 3R, 4R.
(+)-Thalictrifoline(3)是由光学拆分的(+)-8-oxo-13-羧基四氢protoberberine(13)合成的,其绝对构型是通过与(+)-18的相关性建立的。这确定了(+)-水杨三茶碱(3)的绝对构型为13R,14R aria(+)-丙烯醛酸甲酯(9)的3R,4R。
