Description and Uses
3,4-Dimethoxyphenylboronic acid can be used:
- As a substrate in the cross-coupling reaction with 5,7-dichloropyrido[4,3-d]pyrimidine catalyzed by palladium.
- As a starting material for the synthesis of buflavine 1, a natural alkaloid.
- In one of the key synthetic steps for the preparation of lipidated malarial glycosylphosphatidylinositols (GPI) disaccharide.
- To prepare 3,3″,4,4″-tetramethoxy-1,1′:4′,1″-terphenyl by reacting with 1,4-dibromobenzene using Pd catalyst.
