1,3-isoquinolinedicarboxylic acid, 1,2,3,4-tetrahydro-, 3-butyl ester, (1S)-

I look at this question and ask about the chemical structure of (1S) -. However, the words "1% 2C3-isoprene diacid, 1% 2C2% 2C3% 2C4-tetrahydro-, 3-furan" are involved. In the field of chemistry, it is necessary to analyze their characteristics and associations in detail to obtain the exact structure of (1S) -.
1,3-isoprene diacids have the structure of alkenyl and carboxyl groups, and the spatial arrangement and interaction of alkenyl bonds and carboxyl groups affect their chemical properties. And 1,2,3,4-tetrahydro-, or an unsaturated structure is hydrogenated to form a saturated or partially saturated state. As for 3-furan, the furan ring has unique aromatic properties, and its position and connection mode in the overall structure are also critical.
(1S) -, the specific configuration in the chiral structure is often indicated by the S configuration. To clarify the details, when the atoms or groups in the molecule are arranged in space, according to the Cahn-Ingold-Prelog rule, compare the atomic numbers of the connected atoms and the priority of the groups to determine the configuration.
Overall, due to the limited information given, it can only be inferred that the (1S) -structure must involve the chiral center and is related to the chemical structural units mentioned above. Or it can be constructed from 1,3-isoprene acid, 1,2,3,4-tetrahydro-derivative and 3-furan ring, in which the chiral center affects the overall spatial conformation and chemical activity of the molecule. However, in order to determine its precise chemical structure, more information such as bonding relationships and stereochemical details are needed to be determined.

(1S) -substance, its physical properties are specific. 1% 2C3-pentylenedioic acid, this substance presents a specific chemical image, and its properties are controlled by molecules. In the anti-chemical system, its surface shows the universality of the alkenedioic acid. It is acidic and can be neutralized and reversed to form a phase. The density of the carboxyl group in its acidic weak molecule is low, and the lower the density of the carboxyl group peripheral cloud, the more acidic the phase is.
1% 2C2% 2C3% 2C4-tetrathene-substance, the tetrathene makes it have a certain harmony. In terms of physical properties, the melting temperature and density of homologues with higher degree of non-harmony will vary depending on the change of the degree of harmony. The molecular force changes due to the melting, and the melting effect is affected by the melting. Generally speaking, when the degree of harmony increases, the molecular force is fixed, and the melting temperature may be the same as the melting phase.
3-monool, the existence of the alcohol group determines the direction of its physical rationality. The alkyl group can form a alkyl group, which makes the melting temperature a non-alcoholic compound with similar molecular weight. Its solubility is also affected by the alkyl group. Due to the water-based nature of the alkyl group, it can be dissolved in water to a certain extent, and the carbon content increases, and the solubility decreases gradually. Due to the hydrophobicity of the carbon.
(1S) - A substance has both the above-mentioned basic properties, and is affected by the interaction of molecular integers and groups in terms of physicality. Its density, molecular density and molecular weight vary. The solubility needs to consider the solubility and force of each group. In this way, it is a kind of physical reason that multiple groups interact with each other.

In plants, or in physiological processes such as hormone control; in physical processes, or in the synthesis phase of physical substances, it affects the normal operation of the system.
To the main use of (1S) -, or in chiral synthesis. Because of its specific chiral shape, in chiral synthesis, it can be used for chiral production, leading to a specific chiral direction, and achieving a high degree of chiral production. This is important to improve the efficiency of the product and reduce side effects. Or in the synthesis of some refined chemical products, using their chiral characteristics, chiral materials with special functions are used in cutting-edge technologies such as light and light.

To prepare (1S) -1,3-isoprene-diacetate, 1,2,3,4-tetrahydro-, 3-nonanol compounds, the method is as follows:
to prepare (1S) -1,3-isoprene-diacetate, a suitable starting material can be taken first, and the asymmetric catalytic reaction is carried out with a chiral catalyst. If a metal complex with specific chirality is selected as a catalyst, the allyl-containing substrate and acetic anhydride are subjected to mild reaction conditions, such as a controlled temperature of 20 to 30 degrees Celsius, in an inert gas-protected reaction environment, and an organic solvent such as dichloromethane is used as the reaction medium. After the nucleophilic substitution reaction, the hydrogen on the allyl is replaced by acetate, and the target product can be obtained, and the three-dimensional configuration of the product can be better controlled.
Preparation of 1,2,3,4-tetrahydrogen-, suitable unsaturated hydrocarbon feedstocks can be selected, such as compounds containing conjugated double bonds. Catalytic hydrogenation reaction is carried out in a hydrogen atmosphere with a noble metal catalyst, such as a palladium-carbon catalyst. The reaction temperature can be controlled at 50 to 80 degrees Celsius, the pressure is maintained in a certain range, such as one to three atmospheres, and the double bonds are hydrogenated one by one in alcoholic solvents such as ethanol to obtain the product of 1, 2, 3, 4-tetrahydro.
As for the synthesis of 3-nonanol, it can be started from a suitable aldehyde or ketone. If heptanal is reacted with ethyl Grignard reagent, in anhydrous ether and other ether solvents, at low temperature, the carbon anion of Grignard reagent performs nucleophilic addition to the carbonyl group of heptanal, and then hydrolyzes to obtain 3-nonanol. The target product can also be obtained by reacting with corresponding ketones and suitable organometallic reagents. The reaction process requires strict control of the reaction conditions to ensure the purity and yield of the product.
