8-Meth-oxy-3,3,5-trimethyl-3,11-dihydro-pyrano[3,2-a]carbazole.

ABSTRACT: In the title compound, C(19)H(19)NO(2), commonly called koenimbine, the pyran ring adopts a sofa conformation. The carbazole ring system is planar [r.m.s. deviation = 0.063?(1)?Å]. A C(10) zigzag chain running along the b axis is formed through inter-molecular C-H?O hydrogen bonds. The chains are linked via weak C-H?? and N-H?? inter-actions.

In the title compound, C(19)H(19)NO(2), commonly called koenimbine, the pyran ring adopts a sofa conformation. The carbazole ring system is planar [r.m.s. deviation = 0.063 (1) Å]. A C(10) zigzag chain running along the b axis is formed through inter-molecular C-H⋯O hydrogen bonds. The chains are linked via weak C-H⋯π and N-H⋯π inter-actions. ...[more]

rac-Dimethyl 5-oxo-2-[(2,4,4-trimethyl-pentan-2-yl)amino]-4,5-dihydro-pyrano[3,2-c]chromene-3,4-dicarboxyl-ate.

Project description:The title compound, C(24)H(29)NO(7), is asymmetric with a chiral centre located in the pyran ring and crystallizes as a racemate. The coumarin ring system and the fused pyran ring make a dihedral angle of 10.46 (8)°. A short intra-molecular N-H⋯O hydrogen bond between the amino group and the vicinal carbonyl group generates an S(6) ring. Inter-molecular C-H⋯O inter-actions contribute to the stability of the crystal structure.

2,2,10-Trimethyl-2,3-dihydro-pyrano[2,3-a]carbazol-4(11H)-one.

Project description:The title compound, C(18)H(17)NO(2), was prepared from 1-hydr-oxy-8-methyl-carbazole and 3,3-dimethyl-acrylic acid with trifluoro-acetic acid as the cyclization catalyst. Due to the -CMe(2)- group, the mol-ecule is not quite planar. The packing is dominated by the strong N-H?O hydrogen bonds and some weaker C-H?O and C-H?? inter-actions. ?-? Stacking inter-actions [centroid-centroid separation = 3.806?(2)?Å] join neighboring mol-ecules into loosely connected inversion dimers.

2,2,9-Trimethyl-2,3-dihydro-pyrano[2,3-a]carbazol-4-(11H)-one.

Project description:The title compound, C(18)H(17)NO(2), was prepared from 1-hydr-oxy-7-methyl-carbazole and 3,3-dimethyl-acrylic acid with trifluoro-acetic acid as the cyclization catalyst. The mol-ecules contain an essentially planar 6-methyl-indole unit. The second aromatic ring is significantly bent away from the plane of this unit, with maximum deviations of 0.171?(1) and 0.185?(1)?Å for two of the C atoms. In the crystal structure, there are neither N-H?O hydrogen bonds nor ?-? stacking between the aromatic sections of neighboring mol-ecules. There is only one weak C-H?O hydrogen bond and a number of weak C-H?? inter-actions.

Project description:In the title compound, C(14)H(17)NOS, the plane defined by the bridging methyl-ene C atom and its three substituents makes dihedral angles of 14.37?(8)° with the heterocycle and 26.17?(8)° with the phenyl ring, while the dihedral angle between the heterocycle and the phenyl ring is 36.29?(7)°. In the crystal, mol-ecules are linked by C-H?? contacts.

5,11-Dimethyl-6,12-dimeth-oxy-indolo[3,2-b]carbazole.

Project description:The title compound, C(22)H(20)N(2)O(2), was prepared in a twofold Cadogan cyclization followed by double N-methyl-ation. The crystal structure is characterized by a zigzag arrangement of centrosymmetric mol-ecules. The indolocarbazole framework is essentially planar [maximum deviation = 0.028?(2)?Å] and the meth-oxy groups are orthogonal to this plane [C-C-O-C torsion angle = -88.2?(2)°]. The lengths of the C-N bonds are nearly identical and all C-C bonds of the pyrrole subunit are significantly longer than the C-C bonds in the benzene rings.

rac-Diethyl 5-oxo-2-[(2,4,4-trimethyl-pentan-2-yl)amino]-4,5-dihydro-pyrano[3,2-c]chromene-3,4-dicarboxyl-ate.

Project description:The title compound, C(26)H(33)NO(7), comprises a racemic mixture of asymmetric mol-ecules containing one stereogenic centre. The dihedral angle between the mean planes of the fused pyran ring and the coumarin ring system is 8.12?(14)°. The mol-ecular structure features a short N-H?O contact, which generates an S(6) ring motif. The crystal packing are stabilized by C-H?O inter-actions.

The phenyl group on the other ring is in an equatorial position. In the crystal, supra-molecular chains propagating along [100] are formed through C-H?O and C-H?? inter-actions.
