D-tyrosine a method for asymmetric synthesis of

A provided asymmetric syntheses method for D-tyrosine comprises the following steps: performing a condensation reaction on p-hydroxybenzaldehyde and acetylglycine, then performing hydrolysis or alcoholysis to obtain a dehyddroamino acid or ester; and then utilizing rhodium to perform catalytic asymmetric hydrogenation, and performing hydrolysis to obtain a key intermediate D-tyrosine. According to the method, the whole process has no complex separation steps, the preparation technology is simple, a chromatography column is not needed, the reaction steps can be further reduced by utilizing rhodium catalysis asymmetric hydrogenation technology, the production cost is reduced, and the method is extremely suitable for industrialized batch production.
