    (3aR,4S,7R,7aS)-2-Phenyl-4-propyl-3a,4,7,7a-tetrahydro-1H-4,7-epithioisoindole-1,3-dione 8-oxide
    (WILEY-BLACKWELL, 2011) Demircan, Aydin; Sahin, Ertan; Beyazova, Gozde; Karaaslan, Muhsin; Hokelek, Tuncer
    In the tetrahydroisoindole moiety of the title compound, C17H17NO3S, the six-membered ring assumes a boat configuration and the -S=O group bridges the prow and stern of the boat. The phenyl ring is oriented at a dihedral angle of 83.2 (1)degrees with respect to the pyrrole ring. In the crystal, intermolecular C-H center dot center dot center dot O hydrogen bonds link the molecules into a three-dimensional network. A weak C-H center dot center dot center dot pi interaction involving the phenyl ring is also found. The crystal studied was an inversion twin.

    New fatty acid derivatives based on barbiturates and other cyclic beta-dicarbonyl compounds and an acyl migration
    (Springer, 2014) Pesyan, Nader Noroozi; Bagheri, Marziyeh; Sahin, Ertan; Tunç, Tuncay
    The use of DCC, triethylamine and 4-dimethylaminopyridine in dichloromethane provides a general and standard one-pot procedure for the O-acylation of cyclic beta-dicarbonyl compound derivatives (1) with palmitic and stearic acids which have long hydrocarbon tails, to synthesis of new type of fatty acid derivative in good to excellent yields. Structure elucidation was carried out by FT-IR, H-1 NMR and C-13 NMR spectroscopy techniques. The acyl migration was also found in results and the corresponding structure was characterized by X-ray crystallography. A proposed mechanism was discussed for the formation of products.
