A facile synthetic route to diazepinone derivatives via ring closing metathesis and its application for human cytidine deaminase inhibitors

초록

A variety of diazepinone derivatives were prepared from alpha-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 (K-1 = 145.97 +/- 4.87 nM) against human cytidine deaminase.
