Problems solved by technology

[0008] At present, there are few studies on the analysis and separation methods of benzoylcorylide enantiomers in the prior art, and there are some problems and deficiencies in the only exploratory studies, such as the amylose-amylose-coated silica gel surface in the chromatographic column. Tris-(3,5-dimethylphenylcarbamate) filler has less difference in interaction with benzoylcorylide enantiomers and lower stereoselectivity, making benzoylcorylide Lactone enantiomers cannot be separated efficiently

Abstract

The invention discloses a method for analyzing and separating Corey lactone benzoate enantiomers through an HPLC by means of a direct-chain starch type chiral chromatographic column with positive phase mixed solvent as the flowing phase. The method can easily, accurately and efficiently analyze and separate the Corey lactone benzoate enantiomers, and therefore the quality of the Corey lactone benzoate enantiomers is controlled. The method can also be used for preparing high-purity single-optical-activity Corey lactone benzoate.

Description

technical field [0001] The invention relates to a chromatographic analysis and separation method, in particular to a method for analyzing and separating the enantiomers of benzoylcoriletone by high-performance liquid chromatography. technical background [0002] Prostaglandins (PGs for short) are a class of important substances with endogenous physiological activities, which widely exist in various tissues in the body and are important mediators of various physiological processes. Due to the extremely low content in the human body, prostaglandin drugs are mainly synthesized clinically. Benzoyl cori lactone (Corey lactone benzoate) is a common starting material for the synthesis of prostaglandin drugs, and its molecular formula is C 15 h 16 o 5 , chemical name: 5-(benzoyloxy)hexahydro-4-(hydroxymethyl)-2H-cyclopenta[b]furan-2-one, common name: benzoylcorylide , the structural formula is: [0003] [0004] The molecule contains four chiral centers, and theoretically th...
