| Abstract: | The Michael reactions of 4-hydroxyeoumarins with p-quinones in different conditions and their reaction mechanism have been reviewed.4-Hydroxycoumafins reacted with 1,4-benzoquinone in aqueous acetone to afford 2,3-disubstituted-1,4-benzoquinones,with 1,4-naphthoquinone to give corresponding derivatives.The zwitterions were synthesized when 4-hydroxycoumarins reacted with 1,4-benzoquinoe in the presence of pyridine in aqueous acetone.In the similar condition,the corresponding 4-hydroxyquinolinone zwitterions... |
