The preparation of 1,7-di(pyridin-3-yl)-heptan-4-ol (1), an important intermediate in the synthesis of a series of novel cancer multidrug resistance (CMR) chemosensitizers, has been accomplished in high overall yield via the new bis-Wittig reagent 1,5-bis(triphenylphosphonium)pentan-3-ol dichloride (6), that can also be used in the preparation of other members of the class of CMRs.
1,7-二(吡啶-3-基)-庚烷-4-醇(1)是一系列新型癌症多药耐药(CMR)化学增敏剂合成的重要中间体通过新的双维蒂希试剂 1,5-双(三苯基鏻)戊烷-3-醇二氯化物 (6) 产生的产量,也可用于制备 CMR 类的其他成员。
