NOVEL METHOD FOR PRODUCING ANTIBODY-IMMUNOSTIMULATOR CONJUGATE

The purpose of the present invention is to provide a novel stereoselective method for preparing a cyclic dinucleotide derivative and a production intermediate therefor, which can be used for an antibody-immunostimulant conjugate. Also provided is a method for producing a cyclic dinucleotide-linker a...

More Information
Summary:The purpose of the present invention is to provide a novel stereoselective method for preparing a cyclic dinucleotide derivative and a production intermediate therefor, which can be used for an antibody-immunostimulant conjugate. Also provided is a method for producing a cyclic dinucleotide-linker and an antibody-immunostimulant conjugate while using the above production method. Further provided is a method for preparing a cyclic dinucleotide derivative, the method including the step of subjecting a compound (I) and a compound (IV) to stereoselective condensation using an optically active phosphitylating agent (Rc-II) or (Sc-II).
