| titleOfInvention |
Optically active erythro-3-amino-2-hydroxybutyric esters and process for preparing said esters |
| abstract |
The present invention is to provide a method for producingnan optically active erythro-3-amino-2-hydroxybutyric ester asnan important intermediate of pharmaceutical agents,nspecifically HIV protease inhibitor, at a high purity and atna high yield. n More specifically, the present invention relates to anmethod for producing an optically active erythro-3-amino-2-hydroxybutyricnester, ncompwashing oxidizing the hydroxyl group at the 2-position ofnan optically active 3-amino-2-hydroxybutyric ester, opticallynactive at 3-position, as represented by the formula (I);n n(wherein R 1 represents phenyl group or cyclohexyl group; R 2 nrepresents a protective group and R 3 represents alcoholnresidue; the steric configuration of *1 represents Snconfiguration or R configuration), and then reducingnerythro-selectively the resulting product by using aluminiumnalkoxide. |
