Diethyl 2-amino-5-[(E)-(1-methyl-1H-pyrrol-2-yl)methylideneamino]thiophene-3,4-dicarboxylate
The structure of the title compound, C(16)H(19)N(3)O(4)S, shows the planes described by the thio-phene and the pyrroles are twisted by 17.06 (4)°. Additionally, the structure shows the azomethine bond adopts the E configuration, while the pyrrole is disordered as a heterocycle flip [occupancy ratio 0.729 (5):0.271 (5)]. The three-dimensional network is well packed and involves N-H⋯O hydrogen bo...

In the title compound, C(18)H(20)N(4)O(6), the dihedral angle between the two fused five-membered rings in the glycoluril unit is 64.42 (2)°. The crystal structure features inter-molecular N-H⋯O and C-H⋯O interactions. An intramolecular C-H⋯O contact is also present.
متن کامل[Experimental study of the anti-inflammatory and analgesic effects of diethyl 1,3-dicyclohexyl- 1,2,3,6-tetrahydropyrimidine-4,5-dicarboxylate].
OBJECTIVE To study the anti-inflammatory and analgesic activities of diethyl 1,3-dicyclohexyl-1,2,3,6-tetrahydropyrimidine-4,5-dicarboxylate (ZL-5010) in vivo and in vitro. METHODS The analgesic effect of ZL-5010 was evaluated by acetic acid-induced writhing response in mice, and the anti-inflammatory effects was assessed in mice with xylene-induced ear edema and in rats with carrageenan-indu...
متن کاملHyperconjugation in diethyl ether cation versus diethyl sulfide cation.
Ionization of a molecule can greatly alter its electronic structure as well as its geometric structure. In this collaborative experimental and theoretical study, we examined variance in hyperconjugation upon ionization of diethyl ether (DEE) and diethyl sulfide (DES). We obtained the experimental gas phase vibrational spectra of DEE, DES, DEE(+), DES(+), DEE(+)-Ar, and DES(+)-Ar in the wavenumb...
متن کاملDiethyl pyrazine-2,5-dicarboxylate
The mol-ecule of the title compound, C(10)H(12)N(2)O(4), is located around an inversion center. The carboxyl-ate groups are twisted slightly with respect to the pyrazine ring, making a dihedral angle of 2.76 (19)°. In the crystal, mol-ecules are stacked along the c axis via weak C-H⋯O hydrogen bonds.
