| titleOfInvention | Process for the preparation of optically active erythro-3-amino-2-hydroxybutyric acid derivatives and corresponding esters |
| abstract | Field of the Invention The present invention relates to a process for the preparation of estrologically active erythro-3-amine-2-hydroxybutyric acid esters or the corresponding acids, for example, compounds of this type (2S, RS) having a high degree of purity and high heat. More particularly, the present invention relates to a process for the preparation of (III) optically active erythro-3-amine-2-hydroxy-butyric acid esters of the formula (III): wherein R1 is phenyl or cyclohexyl, and R2 is a protecting radical; Spatial configuration of * 2 with S-stone configuration if * 1 with S-stone configuration or R-stone configuration, if * 1 with R-string configuration. In its invention, it is understood that a third or third / erythro-3-amine-2-hydroxypropylic acid ester of general formula (I) having a 3-position optically active position in the 3-position is generally represented by R1, R2 and R3 in the general formula (III). and the spatial position of * 1 is S-or R-stacked - it is oxidized, and then the resulting (II) general formula 3-amino-2-yloxy acid of formula (I) is wherein R1, R2, R3 and * 1 are (I). ) as described in the general formula - a 2-position pottery tube is subjected to an erythrocyte selective shrinkage using a monofilament boiler. ŕ |
