The present invention relates to a method for producing a 2'-hydroxy-protected nucleoside derivative by reacting a ribonucleoside with an acylating reagent in the presence of a metal complex consisting of a copper compound and an optically active ligand. By the method according to the present invention, a 2'-hydroxy-protected ribonucleoside derivative, which is an important intermediate for producing an oligonucleoside, can be easily produced with good regioselectivity from a nucleoside derivative of which 2',3'-hydroxy groups are not protected.
