Vilsmeier-Haack Reaction with 2,3,3-Trimethyl-3H-benzo[g]indole and Its Conversion into 2-(1-aryl-1H-pyrazol-4-yl)-3,3-dimethyl-3H-benzo[g]indoles
Vilsmeier-Haack reaction of 2,3,3-trimethyl-3H-benzo[g]indole, then aqueous basic work-up, leads to benzo[g]indol-2-ylidene- malondialdehydes. These react with various arylhydrazines and quinolin-2-ylhydrazine to form 3,3-dimethyl-2-(1-aryl-1H-pyrazol-4-yl)- 3H-benzo[g]indoles in good yields.
متن کاملanti-toxoplasma activity of 2-(naphthalene-2-γlthiol)-1h indole.
background: this study was undertaken to evaluate the viability, infectivity and immunity of toxoplasma gondii tachyzoites exposed to 2-(naphthalene-2-ylthio)-1h-indole. methods : tachyzoites of rh strain were incubated in various concentrations of 2- (naphthalene-2-ylthio)-1h-indole (25-800μm) for 1.5 hours. then, they were stained by pi and analyzed by fluorescence-activated cell sorting (f...
متن کامل3-(2-Methyl-2-nitropropyl)-1H-indole
In the title compound, C(12)H(14)N(2)O(2), the indole ring is essentially planar, with an r.m.s. deviation of 0.0136 Å. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into inversion dimers..
متن کاملReaction of formaldehyde with proteins; cross-linking of amino groups with phenol, imidazole, or indole groups.
It has been recognized in recent years that, at elevated temperature or in acid or alkaline solution, formaldehyde can add as methyl01 groups to the amide (1, 2), guanidyl (3-8), and indole groups (9) of proteins. In contrast, the addition product of formaldehyde with amino groups forms instantaneously even at neutrality and low temperatures, but this is an equilibrium reaction and the methyl01...
متن کاملStudies on inclusion complexes of 2-[Substituted arylideamino]-1, 3, 4-thiadiazino [6,5b]indole with β- Cyclodextrin
Inclusion complexes of 2-[Arylidenamino]-1,3,4-thiadiazino[6,5b]indoles have been prepared with β-cyclodextrin so as to increase the solubility of these compounds in polar medium which may increase theirbioaccessibility. The formation of inclusion complexes is known from the study of changes in physical andspectral properties of the compounds. The stability of the inclusion complexes has been s...
