Khilya // Chemistry of Natural Compounds. - 2009. - vol. 45. - № 4.https://dspace.nuft.edu.ua/handle/123456789/3997The reaction of natural isoflavones formononetin and cladrin with primary amines and formalin in the presence of a base catalyst was studied. Several novel substituted 9,10-dihydro-4H,8H-chromeno[8,7-e][1,3]oxazin-4-ones containing alkyl, benzyl, or heterylalkyl substituents in the N-9 position were synthesized.otherisoflavonecladrinformononetinelectrophilic substitution9,10-dihydro-4H,8H-chromeno[8,7-e][1,3]oxazin-4-oneізофлавонформононетинкладринелектрофільне заміщення9,10-дигідро-4H,8H-хромено[8,7-e][1,3]оксазин-4-онизофлавонэлектрофильное замещение9,10-дигидро-4H,8H-хромено[8,7-e][1,3]оксазин-4-онкафедра харчової хіміїArticle
