Ethyl 2-(bromo-meth-yl)-5-meth-oxy-1-phenyl-sulfonyl-1H-indole-3-carboxyl-ate.

ABSTRACT: In the title compound, C(19)H(18)BrNO(5)S, the plane of the phenyl ring forms a dihedral angle of 76.99 (6)° with the indole ring system. The Br atom is disordered over two positions, with site-occupancy factors of 0.833 (14) and 0.167 (14). The mol-ecular structure is stabilized by weak intra-molecular C-H⋯O inter-actions and the crystal packing is stabilized by weak inter-molecular C-H⋯O inter-actions.

Project description:In the title compound, C(23)H(17)F(3)N(2)O(3), an intra-molecular C-H⋯F hydrogen bond generates an S(6) ring motif.

Ethyl 1-acetyl-1H-indole-3-carboxyl-ate.

Project description:The title compound, C(13)H(13)NO(3), was synthesized by acetyl-ation of ethyl 1H-indole-3-carboxyl-ate. The aromatic ring system of the mol-ecule is essentially planar, but the saturated ethyl group is also located within this plane and the overall r.m.s. deviation from planarity is only 0.034?Å. Pairs of C-H?O inter-actions connect mol-ecules into chains along the diagonal of the unit cell. Mol-ecules also form weakly connected dimers via ??? stacking inter-actions of the indole rings with centroid-centroid separations of 3.571?(1)?Å. C-H?? inter-actions between methyl-ene and methyl groups and the indole and benzene ring complete the directional inter-molecular inter-actions found in the crystal structure.
