Abstract

The invention discloses a high performance liquid chromatography method for separating (R) and (S)-1-(α-naphthyl) glycidyl ether. (R), (S)‑1‑(α‑naphthyl) glycidyl ether is an important intermediate for the synthesis of β‑receptor blockers such as natopidil and propranolol, and is widely used in medicine and chemical industry areas, but it is difficult to separate the two. The method of the present invention is based on the cheap carbon octadetaph chromatographic column as a means of separation, and can effectively separate (R)-1-(α-naphthyl) glycidyl ether and (S)-1-(S)- 1‑(α‑naphthyl) glycidyl ether is separated, which greatly reduces the separation cost of (R), (S)‑1‑(α‑naphthyl) glycidyl ether.

Description

technical field [0001] The invention belongs to the field of drug analysis, in particular to a high performance liquid chromatography method for separating (R) and (S)-1-(α-naphthyl) glycidyl ether. Background technique [0002] 1-(α-naphthyl) glycidyl ether is an important intermediate for the synthesis of β-receptor blockers such as naftopidil and propranolol, and is widely used in the fields of medicine and chemical industry (natopidil enantiomer Synthetic Process Optimization of Isomers, Journal of Guangdong Pharmaceutical University, 2019). [0003] 1-(α-naphthyl) glycidyl ether has a chiral center and a pair of enantiomers, namely: (R)-1-(α-naphthyl) glycidyl ether, (S)- 1-(α-naphthyl) glycidyl ether, the chemical structure is as follows: [0004] [0005] (R)-1-(α-Naphthyl)glycidyl ether [0006] [0007] (S)-1-(α-naphthyl)glycidyl ether. [0008] When synthesizing target products with different configurations, the required configurations of 1-(α-naphthyl) g...
