substitution reaction with the azide, thioacetate, and dimethyl malonate anions and benzylamine gives the corresponding substituted products in an enantiomerically pure form with an inversion of the configuration in good yields. The methanolysis of (S)-5,6,7,8-tetrahydroquinolin-8-yl acetate in the presence of potassium carbonate and alkylation of the resulting thiol anion with alkyl halides in a one-pot
对映体纯 (S)-5,6,7,8-四氢喹啉-8-醇 [(S)-1] 和 (R)-8-acetoxy-5,6,7,8-四氢喹啉 [(R)-2 ] 已经通过脂肪酶催化的外消旋 5,6,7,8-四氢喹啉-8-醇 [(')-1] 的动力学乙酰化以优异的化学产率制备。(R)-1 的甲磺酰化,然后与叠氮化物、硫代乙酸根和丙二酸二甲酯阴离子和苄胺发生取代反应,以良好的收率得到对映体纯形式的相应取代产物。(S)-5,6,7,8-四氢喹啉-8-乙酸酯在碳酸钾存在下的甲醇分解和所得硫醇阴离子与卤代烷在单锅反应中的烷基化反应得到 5,6,7 ,8-四氢喹啉-8-基硫醚。
