The [4 + 2] cycloadduct 17 of 2,3-dimethylidene-1,2,3,4-tetrahydro-1,3-methanonaphthalene and 4-phenyl-4H-1,2,4-triazole-3,5-dione (PTAD) was subjected to a tripler-sensitized di-pi-methane rearrangement. Hydrolysis of the resulting urazol 18 gave the hydrocarbon 7. Hydrolysis of 18 at lower base concentrations led to isomeric stable semicarbazides 24 and 25, which were submitted NiO2 or MnO2, oxidation, to give the target compound 7, and oxidation products 26 and 27.

Chemistry of the benzotropone endoperoxides and their conversion into tropolone derivatives: Unusual endoperoxide rearrangements Guney, M; Dastan, A; Balcı, Metin (Wiley, 2005-01-01) The chemistry of two bicyclic endoperoxides, obtained by photooxygenation of 2,3-benzotropone (= 5H-benzocyclohepten-5-one 5) and of its ethyl carboxylate derivative 15, was investigated with the aim of synthesizing the respective benzotropolone derivatives. The reaction of the endoperoxide 10 derived from 5 with thiourea gave the desired benzotropolone, i.e., 6-hvdroxy-5H-benzocyclohepten-5-one (11), in high yield (Scheme 1). On the other hand, the endoperoxide 16 derived from the ethyl carboxylate derivat...
Incorporation of an allene unit into alpha-pinene via beta-elimination Kilbas, Benan; Azizoglu, Akin; Balcı, Metin (Wiley, 2006-01-01) The two double-bond isomers 3-iodo-2,6,6-trimethylbicyclo[3.1.1]hept-2-ene (6b) and 3-iodo-4,6,6-trimethylbicyclo[3.1.1]hept-2-ene (11) were synthesized by reacting 2,6,6-trimethylbicyclo[3.1.1]heptan-3-one (9) with hydrazine, followed by treatment with 12 in the presence of Et3N. Treatment of 11 with t-BuOK as base in diglyme at 220 degrees resulted in the formation of 9 and 6,6-dimethyl-4-methylidene-bicyclo[3.1.1]hept-2-ene (12). For the formation of 9, the cyclic allene 7 is proposed as an intermediate....
Controlled synthesis of substituted benzobasketene derivatives Aydinli, B; Celik, M; Gultekin, MS; Uzun, O; Balcı, Metin (Wiley, 2003-01-01) The addition of benzyne to trans-7,8-dibromobicyclo[4.2.0]octa-2,4-diene (6) led to the formation of dibromide 7. The dehydrobromination of 7 followed by replacement of the Br-atom with a CN substituent gave 9. Photolysis of 9 in acetone at 254 nm yielded the desired monosubstituted benzobasketene derivative 10. Bromination of monobromide 8 followed by dehydrobromination furnished the symmetrically substituted dibromo compound 15. Further bromination of 7 followed by dehydrobromination resulted in the forma...
Enantioselective synthesis of 2-(2-arylcyclopropyl)glycines: Conformationally restricted homophenylalanine analogs Demir, Ayhan Sıtkı; Sesenoglu, O; Ulku, D; Arici, C (Wiley, 2004-01-01) Starting from simple aromatic aldehydes and acetylfuran, (E)-1-(furan-2-yl)-3-arylprop-2-en-1-ones (2) were synthesized in high yields. Cyclopropanation of the C=C bond with trimethylsulfoxonium iodide (Me3SO+I-) furnished (furan-2-yl)(2-arylcyclopropyl)methanones 3 in 90-97% yields. Selective conversion of cyclopropyl ketones to their (E)- and (Z)-oxime ethers 5 and oxazaborolidine-catalyzed stercoselective reduction of the C-N bond followed by separation of the formed diastereoisomers, furnished (2-arylcy...
Synthesis of phenyl-substituted conduritol B and its mechanism of formation Cantekin, Seda; Caliskan, Rasit; Sahin, Ertan; Balcı, Metin (Wiley, 2007-01-01) The phenyl-substituted conduritol B 8 was prepared in racemic form in a five-step sequence starting from 2-phenyl-1,4-benzoquinone(10) (Scheme 1). The reaction mechanism of the key step 12b -> 13 is discussed (Scheme 2).
