Definitions
- the invention discloses a novel method for synthesizing a chiral intermediate of radiipavir.
- the specific synthesis method comprises the following steps: using 1,1-dihalomethylcyclopropane and N-Boc-glycine ethyl ester in an alkaline environment
- a spiro compound is obtained by a ring closure; the spiro compound is hydrolyzed by saponification and deprotected by BOC to give a 5-azaspiro[2,4]heptane-6-carboxylic acid racemate; 5-azaspiro[2 , 4] heptane-6-carboxylic acid racemate was asymmetrically resolved to obtain S-5-azaspiro[2,4]heptane-6-carboxylic acid.
- the invention provides a novel method for synthesizing a chiral intermediate of radiipavir, which improves atomic economy, reduces production cost, is simple in synthesis, convenient in preparation, and is advantageous for industrial
