発明の名称 (英語) PROCESS FOR EFFICIENTLY PRODUCING ALKYLATED CATECHIN
発明の概要(英語) Disclosed is an alkylated catechin derivative. Also disclosed is a process for producing an alkylated catechin derivative. Further disclosed is a process for producing an intermediate for the production of an alkylated catechin derivative. Various types of alkylated catechin compounds such as a compound represented by formula (a) can be synthesized by selectively alkylating a phenolic hydroxy group on ring B of a catechin compound, protecting the remaining phenolic hydroxy groups, reacting the resulting product with a benzoic acid derivative having a protected hydroxy group, and properly deprotecting the resulting product. This process enables the convenient synthesis of an alkylated catechin compound such as methylated catechin or a salt thereof and a useful intermediate.
