How is (2S)-3-(Benzyloxy)-2-hydroxypropyl 4-methylbenzenesulfonate (CAS: 16495-04-8) typically synthesized?

This compound is typically synthesized through a multistep process involving the protection of a hydroxyl group, subsequent alkylation, and sulfonation. Commonly, benzyl chloride and 4-methylbenzenesulfonyl chloride are used as the starting materials. The synthesis involves reactions such as alkylation at the hydroxyl group and then sulfonation to form the final compound, with the use of catalysts and solvents to improve selectivity and yield.
