The Uses of D-(-)-THREO-2-AMINO-1-(4-NITROPHENYL)-1,3-PROPANEDIOL

D-threo-(-)-2-Amino-1-(4-nitrophenyl)-1,3-propanediol is an impurity of Chloramphenicol (C325030), a broad spectrum antibiotic agent obtained from cultures of the soil bacterium Streptomyces venezuel ae.

The Uses of D-(-)-THREO-2-AMINO-1-(4-NITROPHENYL)-1,3-PROPANEDIOL

Chloramphenicol base is the parent 4-nitrophenylpropylamine formed by the hydrolysis of the dichloroacetamide of chloramphenicol and is a degradation product commonly encountered with commercial production of chloramphenicol. Chloramphenicol base has no antibiotic activity but has played an integral role in the synthesis and SAR of new generation antibiotics, notably thiamphenicol and experimental analogues, bromamphenicol and methamphenicol.

The Uses of D-(-)-THREO-2-AMINO-1-(4-NITROPHENYL)-1,3-PROPANEDIOL

(1R,2R)-(-)-2-Amino-1-(4-nitrophenyl)-1,3-propanediol may be used in the preparation of (1R,2R)-(-)-2-dimethylamino-1-(4-nitrophenyl)-1,3-propanediol via N,N-dimethylation. It may also be used as a starting material to synthesize (1R,2R)-1,3-diacetoxy-1-(4-nitrophenyl)-2-propylisothioeyanate [(R,R)-DANI].
