What you are asking about is the investigation of a complex chemical structure. This structural expression is quite complicated, including many chemical groups and modifications. To clarify its specific chemical structure, detailed analysis is required.
Here it is mentioned "5- [ (Z) - (5-hydroxyl-2-oxo-1,2-dihydro-3H-indole-3-subyl) ethyl] -2,4-diethyl-1H-pyrrole-3-carboxylic acid". Let us talk about it one by one.
First, (Z) represents the configuration of a double bond in the structure as cis. The 5-hydroxyl-2-oxo-1,2-dihydro-3H-indole-3-subunit moiety, with indole ring as the core, has hydroxyl substitution at position 5, oxygen group at position 2, and dihydro form at positions 1 and 2, and subunit form at position 3. This subunit is connected to ethyl and constitutes the structural fragment of (5-hydroxy-2-oxo-1,2-dihydro-3H-indole-3-subunit) ethyl.
Furthermore, the main structure is 1H-pyrrole ring, with ethyl substitution at the 2,4 position and carboxylic acid group at the 3 position. Overall, this chemical structure is based on the pyrrole ring and binds the side chain containing the indole structure through a specific connection method.
Such structures are used in the field of organic chemistry or have specific physical and chemical properties and biological activities. Or because of its unique structure, it has potential applications in drug development, materials science, etc. For example, some compounds containing indole and pyrrole structures exhibit antibacterial, anti-inflammatory or as organic optoelectronic materials.
In summary, the chemical structure of this "5- [ (Z) - (5-hydroxyl-2-oxo-1,2-dihydro-3H-indole-3-subunit) ethyl] -2,4-diethyl-1H-pyrrole-3-carboxylic acid" fuses a variety of groups, contains many chemical mysteries, and may bloom in different fields.

What you said is related to chemical substances. This is (Z) - (5-ene-2-oxo-1,2-dihydro-3H-indole-3-subunit) methyl-2,4-dimethyl-1H-pyrrole-3-carboxylic acid.
The physical properties of this substance are as follows:
In terms of melting point, due to the structure containing multiple conjugated systems and polar groups, the intermolecular force is strong, so the melting point is high, but the specific value is difficult to determine due to the precise structure and impurity influence. The boiling point is also difficult to measure accurately due to high temperature or decomposition. < Br > In terms of solubility, because it contains carboxyl groups, subunits and other polar groups, it has a certain solubility in polar solvents such as ethanol and acetone, but has low solubility in non-polar solvents such as n-hexane and benzene.
Appearance may be a solid, in view of the conjugate system, or a certain color, such as yellow or brown solid, because the conjugate structure can absorb visible light.
Density is difficult to accurately predict due to its complex structure. However, due to the presence of light elements such as carbon, hydrogen, oxygen, and nitrogen, and the non-tightly packed structure, the density may be similar to that of common organic solids, less than the density of water.
This is based on its structure and the properties of common organic compounds. The specific physical properties still need to be accurately determined by experiments.

To obtain the synthesis method of 5- [ (Z) - (5-ene-2-oxo-1,2-dioxide-3H-indole-3-subunit) methyl] -2,4-dimethyl-1H-pyrrole-3-carboxylic acid, please refer to the idea of "Tiangong Kaiwu", which is described in ancient Chinese as follows:
First take the appropriate starting material, which should have specific structural units such as ethylene, oxygen, and dioxide, and can be reacted in a specific reaction environment. If in a suitable solvent, prepare the appropriate proportion of reactants, or with the help of a specific catalyst, cause it to undergo chemical changes.
During the reaction process, pay attention to temperature, time and other conditions. If the temperature is too high, it may cause excessive reaction and generate many by-products; if the temperature is too low, the reaction will be delayed or difficult to advance. Time control is also critical. If it is too short, the reaction will not be fully functional, and if it is too long, it may cause material loss and increase costs.
can first cause the alkenyl group in the raw material and the reagent containing methyl groups to undergo reactions such as addition in the appropriate reaction system and catalyzed by the catalyst to form a preliminary carbon-carbon bond connection to form a basic skeleton. Then, for the groups such as oxygen generation and dioxide, through selective oxidation or reduction reactions, the chemical structure is finely adjusted to approach the structure of the target product.
Then through suitable separation and purification means, such as distillation, recrystallization, etc., the residual materials and by-products in the reaction system are removed to obtain a pure 5- [ (Z) - (5-ene-2-oxo-1,2-dioxy-3H-indole-3-subunit) methyl] -2,4-dimethyl-1H-pyrrole-3-carboxylic acid product. In this way, a method of synthesis may be obtained.
