Title:
METHOD FOR PRODUCING CYCLODEXTRIN DERIVATIVE, AND POLYMER THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/002955
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for efficiently producing a desired cyclodextrin derivative at high yield and high purity, and a polymer in which this cyclodextrin derivative is used. Provided are: a method for producing a cyclodextrin derivative, the method including reacting an aminated cyclodextrin derivative shown by formula (B) with an acylating agent in the presence of a protic solvent and an aliphatic amine to obtain an amidated product shown by formula (A), and subsequently purifying the resulting amidated product as necessary; and a polymer in which the resulting high-purity amidated product is used (in the formulas, n, R1, R2, and X are as described in the specification and claims).
