1-(1-Hydroxy-9H-carbazol-2-yl)-3-methylbut-2-en-1-one
The title compound, C(17)H(15)NO(2), was prepared as one of two products of the AlCl(3)/POCl(3)-catalysed reaction of 9-carbazol-1-ol with 3,3-dimethyacrylic acid. It crystallizes with two crystallographically independent mol-ecules, A and B, which are virtually superimposable but not related by any translational or other pseudosymmetry. Both independent mol-ecules are almost planar [r.m.s. dev...

In the title mol-ecule, C24H21NO2, the dihedral angle between the carbazole ring system [with a maximum deviation of 0.052 (2) Å] and the benzene ring is 38.6 (1)°. In the crystal, weak bifurcated (C-H)2⋯O hydrogen bonds link the mol-ecules into chains along [100].

The asymmetric unit of the title compound, C(21)H(26)O(4)S, consists of two independent mol-ecules. In both mol-ecules, intra-molecular O-H⋯O hydrogen bonds stabilize the mol-ecular structure. In the crystal, each mol-ecule and its symmetry-related mol-ecule by twofold rotation form a dimer through a pair of inter-molecular C-H⋯O hydrogen bonds. In one of the mol-ecules, the thio-phene group is...

In the title compound, C(22)H(24)O(5), each of the cyclo-hexenone rings adopts a half-chair conformation. The hy-droxy and carbonyl O atoms face each other and are orientated to allow for the formation of the two intra-molecular O-H⋯O hydrogen bonds which are typical of xanthene derivatives. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into layers parallel to the ab...
متن کامل3-(9H-Carbazol-9-yl)-2H-chromen-2-one
The title compound, C(21)H(13)NO(2), was prepared as an example of a new synthesis of carbazoles from a cyclic dibenzo-iodo-lium salt via a twofold Pd-catalysed aryl-ation of a primary amine. The two essentially planar π-subsystems [maximum deviations from the mean square plane of 0.038 (2) Å in the carbazole and 0.059 (2) Å in the coumarine unit] open a dihedral angle of 63.05 (4)°. Two mol-ec...
