摘要 以L-二对甲苯甲酰基酒石酸为拆分试剂,通过化学拆分法得到了旋光异构体(R)-6-(2-氨基-1-羟乙基)-2,2-二甲基-1,3-苯并二氧芑,产率高且光学纯度大于98%ee. An efficient preparation of (R)-6-(2-amino-1-hydroxyethyl)-2,2-dimethyl-1,3-benzodioxine by a chemical resolution in the presence of (-)-di(p-toluoyl)-L-tartaric acid was described. The yield of resolution is high, with the enantiomeric excess being more than 98%.
