A concise, general, and high-yielding method for the preparation of N(G)-aminoguanidines from primary amines is reported. Using available and readily prepared materials, primary amines are converted to protected N(G)-aminoguanidines in a one-pot procedure. The method has been successfully applied to a number of examples including the syntheses of four nitric oxide synthase (NOS) inhibitors. The inhibitors
报道了一种由伯胺制备N(G)-氨基胍的简洁,通用,高产的方法。使用可用且易于制备的材料,伯胺可通过一锅法将伯胺转化为受保护的N(G)-氨基胍。该方法已成功应用于许多实例,包括四种一氧化氮合酶(NOS)抑制剂的合成。研究了制备的抑制剂作为竞争性抑制剂和NOS诱导型亚型(iNOS)的机械失活剂。另外,所制备的四种抑制剂之一,N(G)-氨基-N(G)-2,2,2,2-三氟乙基-L-精氨酸19,显示出独特的抑制iNOS形成NO和防止NADPH消耗的能力。没有不可逆转的酶失活。
