We hereby report the first synthesis of novel class of compounds, 5,5'-carbonyl-bis(5,6-dihydro-4H-thieno- and furo-[2,3-c]pyrrol-4-one starting from methyl 2-(2-methoxy-2-oxoethyl) thiophene- and furan-3-carboxylate, respectively. The ester functionalities connected to methylene group were regiospecifically converted to the desired monoacyl azides. Curtius rearrangement of acyl azides followed by hydrolysis of the formed isocyanates gave the symmetrical urea derivatives. Cyclization of the ester groups provided the target compounds.

New synthetic methodology for construction of the 3,4-dihydroquinolin-2-one skeleton
Dengiz, Çağatay (2013-01-01)
We hereby report a new method for preparation of 3,4-dihydroquinolin-2(2H)-one starting from the methyl 2-(2-carboxyethyl)benzoic acid. The acid functionality, adjacent to the methylene, was regiospecifically converted to the desired methyl ester and the remaining acid functionality was transferred into acyl azide. Curtius rearrangement of acyl azide followed by trapping with aniline and alcohols provided the corresponding urea and urethane derivatives. Hydrolysis of methyl ester groups gave the acids. Ring...
Facile synthesis of novel 7-aminofuro- and 7-aminothieno[2,3-d]pyridazin-4(5H)-one and 4-aminophthalazin-1(2H)-ones
Koza, Gani; Keskin, Selbi; Ozer, Merve Sinem; Cengiz, Betul; ŞAHİN, Ertan; Balcı, Metin (2013-01-07)
We hereby report the synthesis of a novel class of compounds, 7-aminofuro- and 7-aminothieno[2,3-d]pyridazin-4(5H)-one and 4-aminophthalazin-1(2H)-ones starting from methyl 2-(2-methoxy-2-oxoethyl)furan- and thiophene-3-carboxylate and methyl 2-(2-methoxy-2-oxoethyl)benzoate. The ester functionalities connected directly to the aromatic ring were regiospecifically converted to the acid, whereas methylene groups were oxidized to the corresponding ketoesters. Reaction of the ketoesters with hydrazine provided ...
A novel synthesis of 1,2,4-oxadiazoles and isoxazoles
KIVRAK, Arif; Zora, Metin (Elsevier BV, 2014-01-28)
A novel synthesis of 1,2,4-oxadiazoles and isoxazoles is described by utilizing the reactions between amidoximes and alpha,beta-alkynic aldehydes and/or ketones. Conjugate addition products, obtained from amidoximes and alpha,beta-alkynic aldehydes and/or ketones, afford 1,2,4-oxadiazoles and isoxazoles when treated with bases and acids, respectively. 1,2,4-Oxadiazoles can also be synthesized directly from amidoximes and alpha,beta-alkynic aldehydes in a one-pot manner under basic conditions. The reactions ...
The Chemistry of Ethyl 3-(2-Ethoxy-2-oxoethyl)-1H-indole-2-carboxylate: Synthesis of Pyrimido[4,5-b]indoles and Diethyl 4-Hydroxyquinoline-2,3-dicarboxylate via Intramolecular Cyclizations
KAPTI, Tolga; Dengiz, Çağatay; BALCI, METİN (2017-04-01)
We report the synthesis of a new series of 2-oxo-1,2,4,9-tetrahydro- 3H-pyrimido[4,5-b] indole derivatives and diethyl 4-hydroxyquinoline- 2,3-dicarboxylate starting from ethyl 3-(2-ethoxy-2-oxoethyl)- 1H-indole-2-carboxylate. Intramolecular cyclization formed the target ring systems. The key substrates featuring both acyl azide and isocyanate functionalities were prepared from bis(acyl azide) intermediate. The acyl azide functionalities directly connected to methylene groups were regiospecifically converte...
A new and efficient chemoenzymatic route to both enantiomers of alpha '-acetoxy-alpha-methyl and gamma-hydroxy-alpha-methyl cyclic enones
Demir, Ayhan Sıtkı; Findik, H; Kose, E (Elsevier BV, 2004-03-08)
A chemoenzymatic synthesis of both enantiomers of the pharmacologically interesting alpha'-acetoxy-alpha-methyl and gamma-hydroxy-alpha-methyl cyclic enones starting from alpha-methyl-beta-methoxy cyclic enones is reported. Manganese(Ill) acetate-mediated acetoxylation followed by the enzyme-mediated hydrolysis of alpha'-acetoxy enone provides acetoxy enones 1a and 2a and hydroxy enones 1b and 2b with high enantiomeric excesses in good yields. The reduction of the acetoxy and hydroxy enones furnished both e...
