The synthesis of a set of monofluorinated, difluorinated, and non-fluorinated N-acetylated-β3-arginine esters, potential inhibitors of trypsin-like proteases, is described. Elaboration to the target compounds from previously reported enantiopure precursors derived from 3-hydroxypropanal involved 6–7 steps and was achieved in 48–65 % overall yield. The α,α-difluoro-β3-arginine derivative was found to
单氟化,二氟化的一组,和非氟化的合成Ñ -acetylated-β 3 -精氨酸酯,潜在抑制剂胰蛋白酶样蛋白酶,进行说明。先前报道的3-羟基丙醛对映体纯对映体的目标化合物精制涉及6-7个步骤,总产率为48-65%。的α,α-二氟- β 3 -精氨酸衍生物被发现是特别易于水解。三β 3 -精氨酸衍生物为自己的能力抑制胰蛋白酶,α,α二氟化合物中的羧酸盐两性离子的形式被测定中测试。
