摘要：

Room temperature synthesis of benzo[b]pyran-2-imine derivatives via the Knoevenagel condensation of malononitrile and cyanoacetates with salicylaldehyde derivatives over MgO and their transformation to the known coumarins is described. The satisfactory results were obtained with good yields. short reaction time, and simplicity in the experimental procedure.
