An efficient enantioselective synthesis of (−)-chloramphenicol (1) and (+)-thiamphenicol (2) is described. These antibiotics have been synthesized from commercially available 4-nitrobenzaldehyde and 4-(methylthio)benzaldehyde, respectively, using tethered aminohydroxylation and Sharpless asymmetric epoxidation as the chirality inducing steps.
描述了一种有效的对映选择性合成(-)-氯霉素(1)和(+)-噻吩酚(2)。这些抗生素已分别通过束缚的氨基羟基化和Sharpless不对称环氧化作为手性诱导步骤,分别由市售的4-硝基苯甲醛和4-(甲硫基)苯甲醛合成。
