Abstract

A simple and efficient one-pot synthesis of biologically interesting spirooxindole derivatives bearing hexahydroquinoline skeleton was accomplished by EDDA-catalyzed, three-component reactions between isatins, malononitrile, and enaminones in good yields. The value of this methodology lies in its inexpensive and nontoxic organocatalyst, mild reaction conditions, and ease of handling.
