A new approach to the synthesis of Tekturna, a recently marketed drug for hypertension, takes advantage of a modified protocol of the Stoltz palladium-catalyzed asymmetric allylation with a t-BuPHOX ligand for the synthesis of allylated acyclic alkyl aryl ketones. The method led to an α-isopropyl α-allyl aryl ketone in 90% yield and 88 to 91% ee, which was used in the synthesis of an advanced intermediate
合成Tekturna(一种新近上市的高血压药物)的新方法利用Stoltz钯催化的带有t- BuPHOX配体的不对称烯丙基化的改进方案来合成烯丙基化的无环烷基芳基酮。该方法产生的α-异丙基α-烯丙基芳基酮的收率为90%,ee为88%至91%,用于合成向Tekturna的高级中间体。质子添加剂,如BHT(2,6-二-甲有益效果叔丁基- p发现甲酚),对时间和反应的对映选择性。
