1-Methoxy-11H-benzo[b]fluoren-11-one
In the title compound, C18H12O2, the non-H atoms are nearly coplanar, the maximum atomic deviation being 0.113 (2) Å. π-π stacking is observed in the crystal structure, the shortest centroid-centroid distance being 3.5983 (19) Å. The mol-ecular packing is further stabilized by weak C-H⋯O hydrogen bonds, forming an infinite chain along [100] and generating a C(6) motif.

The title compound, C(17)H(10)O(2), is nearly planar, the maximum atomic deviation being 0.053 (2) Å. In the mol-ecule, an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, inversion-related mol-ecules are linked by pairs of weak C-H⋯O hydrogen bonds, forming dimers. π-π stacking is observed in the crystal structure, the closest centroid-centroid distance being 3...
متن کاملConcise copper-catalyzed one-pot tandem synthesis of benzimidazo[1,2-b]isoquinolin-11-one derivatives.
A simple and efficient copper-catalyzed one-pot tandem method has been developed for synthesis of benzimidazo[1,2-b]isoquinolin-11-one derivatives via reactions of substituted 2-halo-N-(2-halophenyl)benzamides with alkyl 2-cyanoacetates or malononitrile under mild conditions.
متن کاملSynthesis of 5 - Methoxycarbonyl - 1 l - methylfuro ( 2 , 3 - c ) acridan - 6 ( 11 H ) ones
The plant family Rutaceae is known [1, 2] to be a prolific source of furoquinoline and pyranoquinoline alkaloids. Along with them acridine alka loids [3, 4] have also been isolated from several members of the same plant family. Recently furanfused acridine systems such as 1 l-methylfuro(2,3-c)acridan-6(l lH)one (1) have also been reported [5-7] to occur in some rutaceous plants. Typical exampl...
متن کاملBenzo[a]fluoren-11-one
The mol-ecule of the title compound, C(17)H(10)O, is nearly planar, the largest deviation from the mean plane being 0.06 Å. The crystal structure is governed by π-π inter-actions, with centroid-centroid distances ranging from .559 to 3.730 Å.
