The crucial step of this strategy was the alkylation of trihydroxydihydrochalcone derivatives 7 and 8 with cinnamyl bromide derivative 13. For this, compounds 7 and 8 were prepared starting from trihydroxyacetophenone (1) in four steps. Then compound 13 was prepared starting from coumaric acid (9) in four steps</dc:description><dc:date>2017</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/20309</dc:identifier><dc:language>en</dc:language><dc:relation>Journal of the Turkish Chemical Society, Section A: Chemistry</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/20309</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
