摘要
The present invention relates to new coumarin derivatives represented by the general formula I CHEM wherein R1 = NH2 or -NHCH=C(CO2C2H5)2, R2 = R3 = R4 = H, R5 = F, R1 = R3 = NHCH=C(CO2C2H5)2, R2 = R4 = R5 = H, R1 = H or OH, R3 = NHCH=C(CO2C2H5)2, R2 = R4 = R5 = H, R1 = OH, R2 = R3 = R4 = H, R5 = -NHCH=C(CO2C2H5)2, R1 = R3 = R5 = H, R2 = CH3 or CF3, R4 = -NHCH=C(CO2C2H5)2, processes for the preparation thereof and their use as intermediates for the synthesis of new coumarin derivatives with potential biological action.
