How is (2S)-2-Amino-3-(benzylsulfanyl)-1-propanol (CAS: 85803-43-6) typically synthesized?

(2S)-2-Amino-3-(benzylsulfanyl)-1-propanol (CAS: 85803-43-6) can be synthesized via a multi-step process starting from benzyl mercaptan and amino compounds. Commonly, the reaction involves the coupling of benzyl mercaptan with an amino compound, followed by amination of the resulting product. This process typically requires a suitable solvent and a catalyst to achieve high yield and selectivity.
