What are the physical properties of 5- [ (bis (2-ethoxy-2-oxyethyl) amino] -4-cyano-2- (ethoxy carbonyl) -3-thiophene ethyl acetate?

5 - [ (Bis (2 - ethoxy - 2 - oxoethoxy) benzyl) ] - 4 - bromobenzyl - 2 - (ethoxy carbonyl allyl) - 3 - ethyl butenate This substance has the following physical properties:

From the perspective of normal temperature and pressure, it is mostly in the state of liquid. Color or colorless and transparent, or slightly yellowish, clear and pure, without obvious impurities.

Smell it, it has a special smell, but it is not a pungent and intolerable smell. This smell may be caused by the interaction of various functional groups in the molecular structure. < Br >
The value of its boiling point, determined by various experiments, is about a certain temperature range. Due to the existence of various forces between molecules, such as van der Waals forces, hydrogen bonds, etc., the boiling point needs to reach a specific value before it can be converted from liquid to gaseous state. In terms of melting point, due to the order of molecular arrangement and the force, there is also a corresponding specific temperature, at which the material state changes from solid to liquid state.

In terms of solubility, in organic solvents such as ethanol and ether, it can exhibit a good mutual solubility state. Due to its molecular structure and organic solvent molecules, it can form a compatible interaction, as shown by the principle of similar compatibility. However, in water, the solubility is not good, because the polarity of molecules and water molecules is quite different, it is difficult to form an effective interaction.

The density is lighter or heavier than that of water, depending on its molecular weight and the degree of intermolecular packing. In many chemical processes and experimental operations, this density property affects the distribution and behavior of substances in the system.

This is part of the physical properties of 5- [ (bis (2-ethoxy-2-oxoethoxy) benzyl) ] -4-bromobenzyl-2 - (ethoxy carbonyl allyl) -3-butenoic acid ethyl ester, which is a key point that needs to be paid attention to in chemical research and application.

What is the synthesis method of 5- [ (bis (2-ethoxy-2-oxyethyl) amino] -4-cyano-2- (ethoxy carbonyl) -3-thiophene ethyl acetate?

To prepare 5- [ (bis (2-ethoxy-2-oxyethyl) ether) ] - 4-hydroxy-2- (ethoxy carbonyl) -3-oxovalerate ethyl ester, you can follow the following ancient method:

First take an appropriate amount of ethanol and react with sodium metal to obtain sodium ethanol, which is the key basic catalyst. Prepare 2-bromoacetate, in the reaction kettle, in an appropriate amount of inert solvent such as toluene, add the prepared sodium ethanol, and the two slowly react to form ethoxy ethyl acetate. This step requires moderate temperature control and does not overreact. < Br >
Then, ethoxy ethyl acetate is used as a group to react with diethyl oxalate under the catalysis of sodium ethanol. During this process, the ratio of reactants and the reaction time are carefully adjusted to make the two fully work to generate 2- (ethoxy carbonyl) -3 -oxoglutarate diethyl ester. This product has a complex structure and harsh reaction conditions. It is necessary to accurately grasp factors such as temperature and catalyst dosage.

Next, diethyl 2- (ethoxy carbonyl) -3 -oxoglutarate is selectively hydrolyzed and decarboxylated. Using dilute acids such as dilute hydrochloric acid as hydrolysis reagents, at a specific temperature and time, one of the ester groups is hydrolyzed and decarboxylated to obtain 2 - (ethoxy carbonyl) - 3 - oxovalerate ethyl ester. This step requires attention to the reaction process and timely termination of the reaction to prevent excessive hydrolysis.

As for bis (2 - ethoxy - 2 - oxyethyl) ether, it can be prepared by reacting ethylene glycol with bromoethane under basic conditions. This ether is reacted with the above 2 - (ethoxy carbonyl) - 3 - oxovalerate ethyl ester under the action of a suitable catalyst, and through a series of complex nucleophilic substitutions, the final result is 5- [ (bis (2 - ethoxy - 2 - oxy ethyl) ether) ] - 4 - hydroxy - 2 - (ethoxy carbonyl) - 3 - oxy valerate ethyl ester.

The whole synthesis process has complicated steps, each step is related to each other, and the requirements for the purity of raw materials and the control of reaction conditions are extremely high. If there is a slight difference, it is difficult to obtain the target product.
