In the title compound, C(17)H(11)F(3)O(2), the dihydro-indene ring is approximately planar with a maximum deviation of 0.024 (2) Å and makes a dihedral angle of 3.17 (8) Å with the adjacent benzene ring. In the crystal, mol-ecules are inter-connected by C-H⋯O inter-actions, forming an infinite chain along the c axis.
In the indane ring system of the title mol-ecule, C(13)H(12)O(4), the hy-droxy-bearing C atom is 0.134 (1) Å out of the plane of the remaining essentially planar atoms (r.m.s. deviation = 0.010 Å). In the crystal, mol-ecules are linked into chains along the b axis by inter-molecular O-H⋯O hydrogen bonds. Additional stabilization is provided by weak inter-molecular C-H⋯O hydrogen bonds.
In present communication a novel series of benzodiazepine derivatives were synthesized from α, β-unsaturated ketones and evaluated for their antimicrobial activities. The α, β-unsaturated ketones were prepared by ClaisenSchimidt Condensation of Indan-1-one with different aldehydes in presence bleaching earth clay and PEG400 as Greener reaction solvent. A novel benzodiazepine derivatives were sy...
The pollen of rye (Secale cereale) was shown to contain a biologically highly active family of glycosides called the secalosides. Secalosides A and B (1), both of molecular formula C46H51-NO24, were found to be epimeric esters of (2-oxo-3-indolyl)acetic acid (4). They are made up, in addition to this heterocyclic aglycon I (4), of three hexose building blocks and a carbocyclic aglycon II, which...
Makran subduction located at the northwest of the Indian Ocean nearby the southern coast of Iran and Pakistan. Makran subduction is the source of tsunamis that threaten southern coast of Iran. In this article, generation and propagation of 1945’s tsunami initiated by Makran subduction is simulated. For the three dimensional generation of the wave, advanced algorithm of Okada is adopted. The CFD...
