Synthesis of cyclohexane derivatives including Br, Cl, N, O, and S at 1,2,4,5-positions: Selectivity in addition reactions Dedicated to Professor Dr. Metin Balci on the occasion of his 65th anniversaryKaya, Afşin AhmetMenzek, AbdullahŞahin, Ertan1,4-Cyclohexadiene2,4-Dinitrobenzenesulfenyl chlorideBrominationSodium azideSulfoneBrominations of mono addition products of 1,4-cyclohexadiene with 2,4-dinitrobenzenesulfenyl chloride (RSCl) selectively gave 1R(S),2R(S),4R(S), 5R(S)-4,5-dibromo-2-(2,4-dinitrophenylthio)cyclohexyl acetate and 1R(S),2R(S),4R(S),5R(S)-4,5-dibromo-2-chlorocyclohexyl)(2,4-dinitrophenylthio) sulfane. From series reactions 7-oxabicyclo[4.1.0]hept-3-ene with reagents, such as RSCl, NaN3, and H2SO4/Ac2O, six 1,2,4,5-tetrasubstituted cyclohexane derivatives including S, O, N, Cl, and Br were selectively obtained. Formations and structures of the products were discussed.PERGAMON-ELSEVIER SCIENCE LTD2014Articlehttps://rdlopen.rawdatalibrary.net/r/gumushane/13201https://doi.org/10.1016/j.tet.2013.11.0271464-5416enTetrahedroninfo:eu-repo/semantics/closedAccessinfo:eu-repo/semantics/articlehttps://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/13201
