text: The present invention is based on the discovery that the stated disadvantages of the prior art can be overcome by allowing a crystalline alpha-maltose, preferably a crystalline alpha-maltose having an alpha-maltose isomer content of 55% or more, to react with a reagent under anhydrous conditions.
text: More particularly, the present invention relates to a process for preparing maltose derivatives, characterized by allowing crystalline alpha-maltose to react with a reagent under anhydrous conditions.
text: To allow crystalline alpha-maltose to react with a reagent in order to prepare a maltose derivative, crystalline alpha-maltose is dissolved or suspended in an organic solvent :
text: As described above, according to the invention, high-purity of maltose derivatives, which are difficult to prepare from conventional anhydrous amorphous maltose or beta-maltose hydrate, can be prepared at a high yield by allowing crystalline alpha-maltose to react with a reagent under anhydrous conditions.
