Synthesis of two alnustone-like natural diarylheptanoids via 4+3 strategyBurmaoǧlu, SerdarÇelik, HülyaGöiksu, SüleymanMaraş, AhmetAltundaş, RamazanSeçen, Hasan1,7-Bis(3,4-dihydroxyphenyl)-hepta-4,6-dien-3-one1,7-bis(4-hydroxyphenyl)- hepta-46-dien-3-oneClaisen-Schmidt condensationdiarylheptanoidin situ enaminationsynthesisThe first total synthesis of (4E,6E)-1,7-bis(3,4-dihydroxyphenyl)-hepta-4, 6-dien-3-one and an alternative synthesis of (4E,6E)-1,7-bis(4-hydroxyphenyl)- hepta-4,6-dien-3-one, two natural diarylheptanoids, mainly based on Claisen-Schmidt condensation were described. The crucial steps of the syntheses were the condensation of OH-protected 4-aryl-2-butanones with OH-protected 3-aryl-acrylaldehydes by the in situ enamination and then deprotection of OH groups to give the corresponding natural diarylheptanoids.TAYLOR & FRANCIS INC2009Articlehttps://rdlopen.rawdatalibrary.net/r/bayburt/12609https://doi.org/10.1080/003979108025420361532-2432enSynthetic Communicationsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://bayburt-rdlopen.rawdatalibrary.net/tr/items/bayburt/12609
