A green procedure for the synthesis of 1,8‐dioxo‐decahydroacridine derivatives is developed undermicrowaveirradiationwithoutcatalyst in water. This method provides several advantages such as excellent yields (86–96%), simple workup procedure, and environment friendliness. J. Heterocyclic Chem., (2010).
An efficient synthesis of some new 1, 8-dioxo-decahydroacridines is achieved via one-pot, three-component condensation of aromatic aldehydes, cyclic diketone and 4-amino benzamide/4-aminophenol. Reaction of these acridines with dimethylacetylene dicarboxylate and triphenylphosphine or cyclohexylisocyanide gives stable phosphorus ylides or 4H-chromene derivatives, respectively, with good yields. Some
A novel cascade reaction of Schiff'sbase was described. The products afforded in the reaction depended on the ratio of the two starting materials. A possible mechanism of the reactions is proposed, which underwent the breaking and new formation of the bond between carbon atom and nitrogen atom.
