- W71978538 abstract "Bu arastirma 1,3-dikarbonil bilesiklerinin mangan(III) asetat ortaminda heteroaromatiksubstitue alkenlere katilmasi ile 5-(2-furil), 5-(2-tiyenil)-4,5-dihidrofuran bilesiklerininsentezine dayanmaktadir.Bu amacla, asetilaseton, etil asetoasetat, dimedon, 5-fenil-1,3-siklohekzandion, 1,3-siklohekzandion 1,3-dikarbonil bilesikleri olarak; 2-(2-fenilvinil)tiyofen, trans-stilben,2-(2-fenilvinil)furan, 2-metil-5-(2-fenilvinil)furan, 2-(1-fenilvinil)tiyofen, 2-(1-fenilvinil)furan, 2-(1-metil-2-fenilvinil)tiyofen heteroaromatik substitue konjuge alkenolarak kullanilmistir. Halkalasma reaksiyonlari sonucunda 5-(2-furil) ve 5-(2-tiyenil)-4,5-dihidrofuran bilesikleri sentezlenmistir.Deneyler 50-70EC sicaklikta, azot atmosferi altinda gerceklestirildi. Urunler kolon vepreparatif ince tabaka kromatografi yontemi kullanilarak saflastirildi. Sentezlenen 4,5-dihidrofuran bilesiklerinin yapilari enstrumental yontemler kullanilarak aydinlatildi.AbstractThis study is based on synthesis of 5-(2-furyl) and 5-(2-tienyl)-4,5-dihydrofurancompounds with the addition of 1,3-dicarbonyl compounds to heteroaromaticsubstituted alkenes mediated manganese(III) acetate.For this purpose, acetylacetone, ethyl acetoacetate, dimedone, 5-phenyl-1,3-cyclohexanedion, 1,3-cyclohexanedion were used as 1,3-dicarbonyl compounds and 2-(2-phenylvinyl)thiophene, 2-(2-phenylvinyl)furan, 2-metyl-5-(2-trans-stilben,phenylvinyl)furan, 2-(1-phenylvinyl)thiophene, 2-(1-phenylvinyl)furan, 2-(1-metyl-2-phenylvinyl)thiophene were used as heteroaromatic substituted alkenes. In the reactions,5-(2-furyl) and 5-(2-tienyl)-4,5-dihydrofuran compounds were synthesised.The experiments were conducted under nitrogen atmosphere at 50-70 oC . All productswere purified by using column and preparative thin layer chromatography. The structureof 4,5-dihydrofuran compounds was identified by instrumental methods." @default.
