A new solid-phase synthesis for ET receptor antagonists suitable for automation is presented. A support bound 2-hydroxybutyric acid derivative was converted to the corresponding ether derivatives using 4-halo-2-methylsulfonylpyrimidines. Subsequent Suzuki coupling with various aryl boronic acids gave the desired antagonists in good yields and purities. Highly potent antagonists with excellent selectivity
提出了一种适用于自动化的ET受体拮抗剂的新型固相合成方法。使用4-卤-2-甲基磺酰基嘧啶将结合有载体的2-羟基丁酸衍生物转化为相应的醚衍生物。随后的铃木与各种芳基硼酸的偶联以良好的收率和纯度提供了所需的拮抗剂。获得了对ET(A)具有优异选择性的高效拮抗剂。
