To prepare (4S) - 3 - [ (2R, 5S) - 5 - (4 - fluorophenyl) - 2 - [ (S) - [ (4 - fluorophenyl) oxy] [4 - [ (trimethylsilyl) oxy] phenyl] ethyl] - 1 - oxo - 5 - [ (trimethylsilyl) oxy] pentyl] - 4 - phenyl - 2 - oxazolidinone, the following methods can be used.

First, start with raw materials containing specific chiral structures, and build the target structure with ingenious reaction sequences. If a compound with a suitable chiral center is selected, it will gradually reach the target molecule through a series of reactions such as nucleophilic substitution, oxidation, and condensation. During nucleophilic substitution, the check point and stereochemistry of the reaction are precisely controlled to ensure the stability of the chiral center configuration; the oxidation step requires the selection of an appropriate oxidant to make the degree of oxidation moderate; in the condensation reaction, the reaction conditions are optimized to improve the reaction yield and selectivity.

Second, the catalytic asymmetric synthesis strategy is adopted. With the help of high-efficiency chiral catalysts, the asymmetric transformation of key steps is realized. Chiral catalysts are carefully screened to consider their affinity for substrates, catalytic activity and stereoselectivity. For example, chiral metal complex catalysts can induce the formation of products of specific configurations in allylation, cyclization and other reactions. And the reaction conditions are mild, environmentally friendly, and in line with the concept of green chemistry.

Third, use the protective group strategy. In view of the many sensitive functional groups in the molecule, it is necessary to introduce and remove the protective group reasonably. For example, easy reactive groups such as hydroxyl groups are protected by protective groups such as trimethylsilyl groups. After the specific reaction is completed, the protective group is removed under mild conditions to restore the activity of the functional group and ensure the smooth progress of the synthesis route. In this way, through multi-method coordination, it is expected to efficiently synthesize this complex organic compound.

(4S) - 3 - [ (2R, 5S) - 5 - (4 - fluorophenyl) - 2 - [ (S) - [ (4 - fluorophenyl) amino] [4 - [ (trimethylsilyl) oxy] phenyl] methyl] - 1 - oxo - 5 - [ (trimethylsilyl) oxy] pentyl] - 4 - phenyl - 2 - oxazolidinone This drug should pay attention to the following things during storage and transportation:

First, temperature and humidity control. This drug is mostly sensitive to temperature and humidity. High temperature may cause the drug to deteriorate, and the efficacy of the drug will be damaged; if the humidity is too high, it may cause the drug to deliquescent and mildew. Therefore, it is necessary to store it in a suitable temperature and humidity environment, such as a specific temperature range, and pay attention to moisture-proof, or use a desiccant to keep it dry.

Second, prevent direct light exposure. Many drugs will have photochemical reactions after being exposed to light, resulting in structural changes and reduced efficacy. The same is true for this drug. During storage and transportation, avoid direct light, and use light-shielding packaging materials, such as brown bottles, light-shielding bags, etc.

Third, avoid vibration and collision. Violent vibration and collision, or damage the drug dosage form, such as breaking the tablet or breaking the capsule. For medicines with special dosage form requirements, it is necessary to handle them with care to ensure smooth transportation, and fill the packaging with buffer materials to reduce the impact of vibration.

Fourth, classified storage. If it is transported and stored with other medicines, it should be classified according to the nature of the medicine to avoid mutual reactions. Especially this medicine contains a special chemical structure, and more attention should be paid to avoid mixing with medicines that may react.

Fifth, follow regulations. Storage and transportation must be strictly in accordance with drug management regulations to ensure compliance in all links. If the transportation must have corresponding qualifications, the storage facilities must meet the prescribed standards.
