Application

Synthesis of Bucetin: Bucetin is synthesized from (2S,3R)-3-amino-2-hydroxy-4-phenylbutyric acid. First, it reacts with di(tert-butyl) dicarbonate to produce intermediate I. Then, intermediate I reacts with L-Leucine tert-butyl ester hydrochloride to produce intermediate II. The use of L-Leucine tert-butyl ester hydrochloride as the preferred raw material can improve the yield and purity of intermediate II. Finally, the protecting groups tert-butoxycarbonyl and tert-butyl ester are removed under acidic and basic conditions, respectively. This operation only requires adjusting the pH of the acid-base system to effectively remove the protecting groups and improve the yield and purity of Bucetin.
 

As a starting raw material for synthesizing other chemicals.
