Optically active erythropro-3-amino-2-hydroxybutyrate and method for producing butyric acid

摘要

The present invention provides a method for producing an optically active erythrosomal 3-amino-2-hydroxybutyrate, which is an important intermediate of HIV protease inhibitors, with a high purity. That is,In formula (R1), R1 represents a phenyl or cyclohexyl group, R2 represents a protecting group, and R3 represents a protecting group. The photosynthesis is characterized by the oxidation of the hydroxyl group of the optically active 3-amino-2-hydroxybutyric ester and the reduction of erythrolide by the aluminum alkoxide The present invention relates to a production method of 3-amino-2-hydroxybutyric acid.
