摘要
Novel tricyclic 1,4-diazepine derivatives pyrido[3',2 '':4,5]thieno[32-e][1,4]diazepin-2-ones have been synthesized. Azetidin-2-one moiety has been incorporated into the 1,4-diazepine scaffold by [2 + 2] cycloaddition of functionalized ketenes to imine C=N bond, and several tetracyclic azetodiazepines which can be considered as potential compounds of biological interest have been prepared. Stereoselectivity of the cycloaddition was proved by NMR and X-ray analysis data.Novel tricyclic 1,4-diazepine derivatives pyrido[3',2 '':4,5]thieno[32-e][1,4]diazepin-2-ones have been synthesized.
