A variety of diazepinone derivatives were prepared from α-amino acids and amino alcohols by a new synthetic methodology based on ring closing metathesis as a key step. The diazepinones were coupled with ribose derivatives to afford novel diazepinone nucleosides. Among them, (4R)-1-ribosyl-4-methyl-3,4-dihydro-1H-1,3-diazepin-2(7H)-one (3) showed a potent inhibitory effect (Ki = 145.97 ± 4.87 nM) against human cytidine deaminase.
通过一种基于环闭合互变的新的合成方法,从α-氨基酸和氨基醇中制备了多种二氮杂庚烯酮衍生物。这些二氮杂庚烯酮与核糖衍生物偶联,生成新型二氮杂庚烯酮核苷。其中,(4R)-1-核糖基-4-甲基-3,4-二氢-1H-1,3-二氮杂庚烯-2(7H)-酮(3)对人细胞胞苷脱氨酶表现出显著的抑制作用(Ki = 145.97 ± 4.87 nM)。
