Synthesis and properties of 4-chloromethyl-6-hydroxycoumarins and 4-(2-benzofuryl)-6-hydroxycoumarins
(2009) Frasinyuk, Mihaylo; Bondarenko, Svetlana; Khilya, Volodimir
New 4-chloromethyl-6-hydroxycoumarins have been obtained by the condensation of hydroquinone derivatives with 4-chloroacetoacetic ester, and have been used for the synthesis of 4-(2-benzofuryl)-6-hydroxycoumarins. Alkylation and acylation of the phenolic hydroxyl of the synthesized 4-(2-benzofuryl)coumarins have been investigated.
Synthesis of formononetin analogs
(2003) Bondarenko, Svetlana; Frasinyuk, Mihaylo; Khilya, Volodimir
Derivatives of the natural isoflavone formononetin were synthesized. Acylation and alkylation of the phenolic hydroxyls and the chromone ring were investigated.
Synthesis of 3',4'-dimethoxyisoflavone derivatives
(2003) Bondarenko, Svetlana; Frasinyuk, Mihaylo; Khilya, Volodimir
2-(Un)substituted-3',4'-dimethoxy-7-hydroxyisoflavones were synthesized. Their derivatives substituted at the phenolic hydroxyl were prepared by alkylation and acylation. Aminomethyl derivatives were also prepared.
Synthesis of pseudobaptigenin analogs
(2003) Bondarenko, Svetlana; Frasinyuk, Mihaylo; Khilya, Volodimir
Homologs of the natural isoflavonoid pseudobaptigenin containing benzodioxane and benzodioxepane fragments were synthesized. Methanesulfonyl, carbamoyl, aminomethyl, and coumarin-containing isoflavone derivatives were prepared.
