Denitrogenative ortho‐arylation, vinylation and methylation of 1,2,3‐benzotriazin‐4‐(3H)‐ones with organic boronic acids catalyzed by nickel complexes to give a wide range of o‐substituted benzamides were demonstrated. Further, the catalytic reaction is successfully applied to the synthesis of the popular hypertensive drugs losartan and irbesartan in high yields.
镍配合物催化了1,2,3-苯并三嗪-4-(3 H)-酮与有机硼酸的脱氮邻位芳基化,乙烯基化和甲基化反应,得到了多种邻位取代的苯甲酰胺。此外,催化反应已成功地以高收率应用于流行的高血压药物氯沙坦和厄贝沙坦的合成。
