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...
متن کامل(2E)-3-(3-Benzyloxyphenyl)-1-(2-hydroxy-5-methylphenyl)prop-2-en-1-one
In the mol-ecule of the title compound, C(23)H(20)O(3), an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. The central benzene ring makes dihedral angles of 80.17 (8) and 16.99 (7)°, respectively, with the benz-yloxy and hy-droxy-methyl phenyl rings. In the crystal, mol-ecules are linked via inter-molecular C-H⋯O hydrogen bonds to form dimers. The dimers are connected by C-H⋯O hydro...

In the title compound, C(24)H(25)NO(7)S, the sulfonyl-bound phenyl ring is approximately perpendicular to the indole ring system [dihedral angle = 87.72 (5)°]. The methyl group of one of the ester units is disordered over two positions with occupancies of 0.527 (13) and 0.473 (13). An intra-molecular C-H⋯O hydrogen bond is observed. In the crystal structure, mol-ecules are linked into a ribbon ...

In the title compound, C(23)H(25)NO(5), the lactam ring adopts an envelope conformation and both eth-oxy-carbonyl side chains show an s-cis conformation: one is nearly planar, the dihedral angle between CO(2) and OCH(2)CH(3) groups being 7.95 (14)° and the other is almost orthogonal, the C-O-C-C torsion angle being 85.33 (9)°. Dimers related by inversion symmetry are stabilized by C-H⋯O hydroge...
