标题:A Convenient Synthesis Of (Z)-4-Hydroxy-N-Desmethyltamoxifen (Endoxifen)
摘要:A Mixture Of The (Z)-And (E)-Isomers Of 4-Hydroxy-N-Desmethyltamoxifen Was Conveniently Prepared In Four Steps. These Geometrical Isomers Were Then Neatly Separated By Semi-Preparative Reverse Phase High Performance Liquid Chromatography (Rp-HPLC) Using Specified Conditions. Additionally,The Isolated E-Isomer Could Be Equilibrated In Aqueous Strong Acid In Acetonitrile Or Trifluoroacetic Acid/dichloromethane To Give A Clean 1: 1 Mixture Of Z/e Isomers That Was Re-Subjected To HPLC Separation. In This Way,Most Of The Undesired (E)-Isomer Could Be Readily Converted To The Desired (Z)-Isomer Providing Quick Access To Over 200 Mg Quantities Of Pure Endoxifen (Z-Isomer),A Potent Antiestrogenic Metabolite Of Tamoxifen Traditionally Used In Breast Cancer Treatment.
