Resolution of racemic cis-3-(2-aminophenylthio)-2-hydroxy-3-(4-methoxyphenyl) propionic acid (2) via the cinchonidine salt 3, and brucine salt 4, isolation of the calcium salts (+)- and (−)-5, as well as their cyclization to enantiomeric 1,5-benzothiazepines (+)- and (−)-1, are described. X-Ray single-crystal analysis reveals (2S, 3S) absolute configuration of (+)-1 on the basis of tentative comparison of CD
通过辛可尼定盐3和brucine盐4拆分外消旋顺式-3-(2-氨基苯硫基)-2-羟基-3-(4-甲氧基苯基)丙酸(2),分离钙盐(+)-和描述了(-)- 5以及它们对对映体1,5-苯并噻氮杂((+)-和(-)- 1的环化。X射线单晶分析揭示了(+)- 1的(2 S,3 S)绝对构型,是根据CD数据与已知的1,4-苯并二氮杂pine衍生物(+)- 8的CD数据的初步比较得出的。配置。
