Abstract:
Provided is a stereoselective synthesis of an intermediate for the preparation of the heterocyclic derivative as a Cap-dependent endonuclease inhibitor. The synthesis process has the advantages of simple operation, higher yield and relatively controllable steroselectivity, such that it is suitable for large-scale production.
