What are the methods for preparing 2-Hydroxy-2-Phenylethyl (R- (-)) -P-Toluenesulphonate?

The method of preparing (R -（ - ）） - p-toluenesulfonic acid 2-hydroxy-2-phenethyl ester has been refined through the ages.
First, it can be started from 2-hydroxy-2-phenylethanol. This alcohol reacts with p-toluenesulfonyl chloride in a suitable solvent, such as pyridine, at low temperature and under stirring conditions. Pyridine can not only act as a base to capture the hydrogen chloride generated by the reaction, but also provide a relatively mild environment for the reaction. The hydroxyl group of 2-hydroxy-2-phenylethanol is nucleophilic, and the sulfonyl group of p-toluenesulfonyl chloride is electrophilic. When the two meet, the hydroxyl group attacks the sulfonyl group, and the chlorine leaves, it becomes the precursor of the target product. This reaction requires strict temperature control. Due to high temperature, it is easy to cause side reactions, such as hydrolysis of p-toluenesulfonyl chloride, or further conversion of the product.
Second, acetophenone is used as the starting material. First, acetophenone is reduced to 2-hydroxy-2-phenylethanol by reducing agents such as sodium borohydride. Sodium borohydride has moderate reduction ability and good selectivity, and can obtain alcohol efficiently. Then, according to the above method of reaction with p-toluenesulfonyl chloride, (R -（ - ）） - p-toluenesulfonate 2-hydroxy-2-phenethyl ester is prepared. The key to this route lies in the stereochemical control of the reduction step. If you want to obtain a specific configuration of the product, you need to choose a stereoselective reducing agent or reaction conditions.
Third, there is also a method of phase transfer catalysis. In the water-organic two-phase system, a phase transfer catalyst such as a quaternary ammonium salt is added. In the presence of alkali, the negative ion of 2-hydroxy-2-phenylethanol can shuttle between the aqueous phase and the organic phase by the power of the phase transfer catalyst, and react with the p-toluenesulfonyl chloride in the organic phase. The advantage of this method is that the reaction conditions are mild, and the two-phase system is convenient for the separation and purification of the product.
All these methods have their own advantages and disadvantages. It is necessary to consider the availability of raw materials, the cost of the reaction, the purity of the product and the configuration requirements and many other factors according to the actual needs.
