ABSTRACT:
The present invention provides a process for preparing a sugar chain asparagine derivative. According to the process, various isolated sugar chain asparagine derivatives useful in the field of the development of pharmaceuticals and the like can be conveniently obtained in a large amount as compared to that of the prior art. The present invention also provides a process for preparing a sugar chain asparagine and a process for preparing a sugar chain via a step for preparing a sugar chain asparagine derivative. The present invention further provides a novel sugar chain asparagine derivative, a sugar chain asparagine and a sugar chain.
