Its color may be colorless and transparent, or it may show a light color such as white due to impurities and molecular structure characteristics.

The solubility of this compound is also an important physical property. In organic solvents, such as common ethanol, acetone, etc., due to the principle of similar miscibility, it exhibits different solubility according to the degree of matching between the polarity of its molecules and the polarity of the solvent. If the molecule contains more polar groups, it has good solubility in polar solvents; if the non-polar part accounts for a large proportion, it is more soluble in non-polar organic solvents.

Melting point and boiling point are also key physical properties. Melting point is the temperature at which a substance changes from a solid state to a liquid state. The melting point of this compound depends on intermolecular forces, such as hydrogen bonds, van der Waals forces, etc. If the intermolecular forces are strong and more energy is required to overcome them, the melting point will be high; vice versa. Boiling point is the temperature at which the liquid state converts to a gas state. It is also affected by intermolecular forces and is also related to external pressures.

In addition, the compound may have certain optical properties. For example, some conjugated structures or special functional groups make them absorb or emit light at specific wavelengths, and have unique absorption peaks or emission peaks in spectral analysis, which can be used for qualitative and quantitative analysis. Its refractive index can reflect the degree of change in the direction of light propagation by substances, and is related to the density of substances and molecular arrangement.

What are the synthesis methods of 8- (2,3-dihydro-1H-indole-1-ylsulfonyl) quinoline?

There are many synthetic methods for 8- (2,3-dihydro-1H-indole-1-ylcarbonyl) benzoic acid, which are described in detail by you below.

One of them is to use 2,3-dihydro-1H-indole-1-formic acid as the starting material. First, it interacts with a suitable halogenating agent, such as sulfoxide chloride, to convert the carboxyl group into an acyl chloride. This acid chloride is then acylated with 8-hydroxybenzoic acid in the presence of a base, such as triethylamine, to obtain the target product. The advantage of this path is that the raw materials are relatively easy to obtain, the reaction steps are clear, and the reaction conditions of each step are mild and easy to control.

Second, start from 2,3-dihydro-1H-indole. First, through N-acylation reaction, the indole nitrogen atom is acylated with a suitable acylation reagent, such as acetyl chloride, under alkali catalysis to generate N-acetyl-2,3-dihydro-1H-indole. After that, it is oxidized with a suitable oxidant, such as potassium permanganate, to convert the acetyl group into a carboxyl group, resulting in 2,3-dihydro-1H-indole-1-carboxylic acid. The next step is the same as the first method, that is, after conversion to acyl chloride, it reacts with 8-hydroxybenzoic acid. Although this method has a little more steps, the reaction selectivity of each step is good and the yield is higher.

Furthermore, 8-halobenzoic acid is reacted with 2,3-dihydro-1H-indole-1-ylmethyl lithium reagent. First, 2,3-dihydro-1H-indole-1-ylmethyl lithium can be prepared by reacting 2,3-dihydro-1H-indole-1-ylmethyl halide with metal lithium at low temperature. Subsequently, the lithium reagent reacts with 8-halobenzoic acid in a suitable solvent, and the target product is obtained after hydrolysis. This path can build key carbon-carbon bonds in one step, which has atomic economy, but the lithium reagent has high activity and harsh reaction conditions, requiring an anhydrous and anaerobic environment.
