Twelve baicalein derivatives, derivatized with 7-ester and 8-aminomethylene groups, were synthesized as cyclin-dependent kinase 1 (CDK1) inhibitors, by the addition of one of four secondary amines to C-8, using the Mannich reaction, followed by mono-esterification with one of three carboxylic acids. Analysis by 1H-, 13C-NMR, and HMBC spectra, as well as a chemical test, confirmed that the esterification occurred at the 7-phenolic hydroxyl position of baicalein but not at the 5- or 6-positions.
