Described is a method for the preparation of renin inhibitors such as aliskiren, and intermediates useful therein. The method introduces a nitrogen-containing intermediate such as a lactone of formula (8). with R4 being a branched C3_6 alkyl. In the preparation of the lactone, or related intermediates, a desired stereochemical configuration can be controlled by starting from a chiral aldehyde satisfying formula (10).
描述了一种用于制备肾素抑制剂如阿利卡西仑的方法,以及其中有用的中间体。该方法引入了一种含氮的中间体,如具有化学式(8)的内酯,其中R4为支链C3_6烷基。在制备内酯或相关中间体时,可以通过从符合化学式(10)的手性醛开始来控制所需的立体化配置。
