This is the name of an organic compound. According to this name, its chemical structure is similar to interpreting ancient secrets, and it needs to be disassembled and analyzed according to a specific method.

" (7,17) -3-oxo-7 - {9 - [ (4,4,5,5,5 - pentafluoropentyl) thio] nonyl} estr-4-en-17-yl acetate". Looking at "estr-4-en" first, it can be seen that this compound has a steroid parent nucleus and has a double bond at the 4th position. "3-oxo" indicates that the 3rd position is a carbonyl group. "17-yl acetate" means that the 17th position is connected to the acetic acid group.

Look again at "7 - {9 - [ (4,4,5,5,5 - pentafluoropentyl) thio] nonyl}", which is the 7-position substituent. Where "9 - [ (4,4,5,5,5 - pentafluoropentyl) thio] nonyl" means that at the 9-position of the nonyl group, a pentafluoropentyl group is connected through the sulfur atom.

Its chemical structure is like a detailed ancient picture, which is slowly revealed according to this clue.

What are the physical properties of (7,17) -3-oxo-7- {9- [ (4,4,5,5,5-pentafluoropentyl) thio] nonyl} estr-4-en-17-yl acetate?

(7,17) - 3-oxo-7 - {9 - [ (4,4,5,5,5-pentafluoropentyl) thio] nonyl} estrogen-4-ene-17-yl acetate, this is an organic compound, and its physical properties are of great research value.

Looking at its properties, it may be a crystalline solid under normal conditions. Due to the orderly arrangement of intermolecular forces, it has a regular lattice structure. Such structures endow it with relatively stable morphology and are not easy to flow freely under conventional conditions.

When it comes to melting point, due to the complex interaction between atoms and groups in the molecule, there are strong van der Waals forces and hydrogen bonds, etc., or the melting point is in a higher range. This is because in order to destroy the ordered arrangement between molecules, more energy needs to be supplied to make it change from solid to liquid.

In terms of solubility, in view of the fact that the molecule contains both hydrophobic long chains of hydrocarbons and pentafluoroamyl sulfide groups, as well as hydrophilic ester groups, it may exhibit good solubility in organic solvents such as chloroform and dichloromethane. Due to the principle of similar solubility, the hydrophobic part can interact with organic solvents. However, the solubility in water is not good, because the hydrophobic part accounts for a large proportion, it is difficult to form effective interactions with water molecules. < Br >
Its density may be slightly higher than that of water, because the molecule contains fluorine and other elements with relatively large atomic mass, and the molecular structure is relatively compact, and the mass per unit volume is relatively high.

In addition, the physical properties of the compound may be affected by external environmental factors. When the temperature increases, the thermal motion of the molecule intensifies, or it affects its crystalline morphology and phase state; and the pressure change may also affect its condensed structure, which in turn affects physical properties such as density.

What are the synthesis methods of (7,17) -3-oxo-7- {9- [ (4,4,5,5,5-pentafluoropentyl) thio] nonyl} estr-4-en-17-yl acetate?

To prepare (7,17) -3-oxo-7- {9- [ (4,4,5,5,5-pentafluoropentyl) thio] nonyl} estr-4-ene-17-yl acetate, there are many methods for synthesis. First, it can be obtained by starting from the key intermediate and undergoing multiple steps of delicate transformation.

First, take a suitable enol structural substrate and react with the haloalkane containing pentafluoropentyl thio group by nucleophilic substitution.

Subsequently, the enol part of the intermediate is oxidized by appropriate means to transform it into the desired 3-oxo structure.

Or another way is found, using the steroid skeleton as the basis, and gradually introducing the side chain. First, the functional group is introduced at a specific position of the steroid, and then the long-chain alkyl group containing sulfur and pentafluoropentyl is connected through the coupling reaction. In this coupling reaction, according to the characteristics of the substrate, the cross-coupling catalyzed by palladium can be selected, etc., and the reaction parameters can be carefully adjusted to promote its efficient progress.

Furthermore, a convergence synthesis strategy can be designed. The steroid part and the sulfur-containing side chain part are constructed separately, and then connected at an appropriate stage. The modification of the steroid part and the synthesis of the side chain can be carried out simultaneously, and finally the splicing can be cleverly carried out, which may reduce the reaction steps and improve the overall synthesis efficiency. Each method requires careful consideration of reaction conditions, such as temperature, solvent, and catalyst dosage, and requires fine monitoring to ensure the purity and yield of the product for the purpose of synthesis.
