Stereospecific syntheses starting from carbo-hydrate precursors of (+)-(R) and (–)-(S)-ethyl iso-propyl methyl phosphates, (+)-(R)-O-ethyl O,S-dimethyl phosphorothioate, and (+)-(R)-ethyl methyl methyl-phosphonate are described; the enantiomeric purity of these compounds was determined by an n.m.r. method involving the use of tris-[3-(heptafluoro-n-propylhydroxy-methylene)-(+)-camphorato]europium(III)
从(+)-(R)和(-)-(S)-乙基异丙基甲基磷酸酯,(+)-(R)-O-乙基O,S-二甲基硫代磷酸酯,描述了(+)-(R)-甲基膦酸乙酯。这些化合物的对映体纯度是通过核磁共振法测定的,该方法涉及使用三-[3-(七氟-正丙基羟基-亚甲基)-(+)-樟脑灯] eur(III)。
