- W493109048 abstract "Bu tez, elektrokimyasal yontemle sentezlenen mangan(III) asetat araciligiyla 3-oksopropannitrillerin konjuge ester ve amitlerle radikalik halkalasma reaksiyonlari temeline dayanmaktadir. Bu reaksiyonlar sonucunda 4-siyano-2,3-dihidrofuran-3-karboksilat ve 4-siyano-2,3-dihidrofuran-3-karboksiamit bilesikleri iyi verimlerle elde edildi.Calismada 3-oksopropannitril olarak; 3-fenil-3-oksopropannitril (1a), 3-(4-metilfenil)-3-oksopropannitril (1b), 3-(4-metoksifenil)-3-oksopropannitril (1c), 3-(4-klorfenil)-3-oksopropannitril (1d), 3-(2-tiyenil)-oksopropannitril (1e), 3-(2-furil)-oksopropannitril (1f) ve 3-(2-benzofuroil)-3-oksopropannitril (1g) ve 4,4-dimetil-3-oksopentannitril (1h); konjuge esterler ve amitler olarak; etil (2E)-3-fenilbut-2-enoat (2a), (2E)-3-fenilbut-2-enamit (2b), etil 3,3-difenilakrilat (2c), 3,3-difenilakrilamit (2d), etil (2E)-tien-2-ilbut-2-enoat (2e) ve (2E)-3-tien-2-ilbut-2-enamit (2f) kullanildi.3-Oksopropannitriller ile mangan(III) asetat araciligiyla yapilan radikalik halkalasma reaksiyonlarinda, tiyenil substitue ester ve amitlerin kullanimiyla elde edilen 2,3-dihidrofuran bilesiklerinin verimleri fenil substitue ester ve amitlerin reaksiyon verimlerine gore daha yuksek oldugu gozlendi.Reaksiyonlar sonucunda elde edilen tum urunler kolon veya preparatif ince tabaka kromatografisi kullanilarak saflastirildi. Bu bilesiklerin yapilari; IR, 1H-NMR, 13C-NMR, LC-MS ve element analizleri ile dogrulandi.Abstract This study is based on the radical cyclizations of 3-oxopropanenitriles with conjugated esters and amides mediated manganese(III) acetate which is synthesized by electrochemical method. By these reactions ethyl 4-cyano-2,3-dihydrofuran-3-carboxylates and 4-cyano-2,3-dihydrofuran-3-carboxamides were obtained in good yields.In this study, 3-phenyl-3-oxopropanenitrile (1a), 3-(4-metylphenyl)-3-oxopropanenitrile (1b), 3-(4-metoxyphenyl)-3-oxopropanenitrile (1c), 3-(4-chlorophenyl)-3-oxopropanenitrile (1d), 3-(2-tienyl)-oxopropanenitrile (1e), 3-(2-furyl)-oxopropanenitrile (1f) 3-(2-benzofuroyl)-3-oxopropanenitrile (1g) and 4,4-dimetyl-3-oxopentanenitrile (1h) compounds were used as 3-oxopropanenitriles and ethyl (2E)-3-phenylbut-2-enoate 2a, (2E)-3-Phenylbut-2-enamide 2b, ethyl 3,3-diphenylacrylate 2c, 3,3-diphenylacrylamide 2d, ethyl (2E)-3-(2-thienyl)but-2-enoate 2e and (2E)-3-(2-thienyl)but-2-enamide 2f compounds were used as conjugated esters and amides.In these radical cyclizations, a noteworthy increase is observed in product yields when phenyl group of conjugated esters and amides is replaced with thienyl group.All products of obtained after reactions were purified by column or preparative thin layer chromatography. All compounds were characterized by IR, 1H-NMR, 13C-NMR, LC-MS and elemental analysis." @default.
