METHOD FOR PRODUCING OPTICALLY ACTIVE SUCCINIMIDE DERIVATIVE AND INTERMEDIATE THEREOF

摘要

Disclosed is a method for producing an optically active succinimide derivative which is a key intermediate of (3R)-2'-(4-bromo-2-fluorobenzyl)spiro[pyrrolidine-3,4'(1'H)-pyrrolo[1,2-a]pyrazine]-1',2,3',5(2'H)-tetraone. The method for producing an optically active succinimide derivative comprises the following reaction steps.
