Stereochemically pure di(1 R,2 S,5 R)-menthyl ( S)- and ( R)-2-hydroxy-3-chloropropylphosphonates were synthesized by reaction of di(1 R,2 S,5 R)-menthyl ketophosphonate with chiral complexes prepared from sodium borohydride and ( R, R) -( +)-tartaric acid or with ( S, S)-(-)-tartaric acid. Dimenthyl 2-hydroxy-3-chloropropylphosphonate was utilized as a chiron for the preparation of biologically active
通过二(1R,2S,5R)-薄荷基酮膦酸酯反应合成立体化学纯的二(1R,2S,5R)-薄荷酯(S)-和(R)-2-羟基-3-氯丙基膦酸酯与由硼氢化钠和(R,R)-(+)-酒石酸或与(S,S)-(-)-酒石酸制备的手性配合物。2-羟基-3-氯丙基膦酸二甲酯被用作制备生物活性产品的chiron。
