2-(Furan-2-yl)-5-(2-nitro-benz-yl)-2,3-dihydro-1,5-benzothia-zepin-4(5H)-one.

ABSTRACT: The title compound, C(20)H(16)N(2)O(4)S, was prepared by introduction of a 2-nitro-benzyl group to 2-(furan-2-yl)-2,3-dihydro-1,5-benzothia-zepin-4(5H)-one via an alkaline-catalysed reaction. The thia-zepine ring adopts a twist-boat conformation. The furan ring is oriented at dihedral angles of 56.75?(14) and 10.82?(14)° with respect to the two benzene rings, while the two benzene rings make a dihedral angle of 62.96?(10)°. Weak inter-molecular C-H?O hydrogen bonds occur in the crystal structure.

Project description:In the title compound, C18H17NO3S, the seven-membered thia-zepine ring adopts a slightly distorted sofa conformation. The dihedral angle between the mean plane of the benzothia-zepine ring system and the benzene ring is 5.9 (1)°. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯S hydrogen bond, which generates an S(7) ring motif. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link inversion-related mol-ecules into dimers, incorporating R 1 (2)(6) and R 2 (2)(8) ring motifs; the acceptor O atom is bifurcated. These dimers are further linked by C-H⋯O hydrogen bonds, forming supra-molecular tapes running along the a axis. These are connected into the three-dimensional architecture by C-H⋯π inter-actions.

Project description:In the title compound, C18H17NO3S, the thia-zepine ring adopts a slightly distorted twist-boat conformation. The dihedral angle between the mean plane of the benzo-thia-zepin ring system and the benzene ring is 60.3?(1)°. In the crystal, mol-ecules are linked by two pairs of inversion-related N-H?O and C-H?O hydrogen bonds, generating alternating R 2 (2)(8) and R 2 (2)(6) ring motifs, respectively, in a zigzag supra-molecular chain that runs along the c axis. These chains stack along the a axis via S?C [3.424?(2)?Å] contacts. A three-dimensional supra-molecular network is consolidated by C-H?? and ?-? inter-actions [inter-centroid distance between di-meth-oxy-benzene rings = 3.815?(1)?Å]. The crystal studied was a non-merohedral twin, with a refined value of the minor twin fraction of 0.2477?(6) .
