Abstract

To access useful heterocycles in medicinal chemistry such as pyridazinones, dihydropyrimidinones, and dihydropyrimidinthiones, a “green” mild and highly efficient one- pot triple cascade was developed involving a Claisen–decarboxylation, electrophilic reaction, and subsequent heterocyclization. In addition, indazoles and benzofurans could also be constructed via a double cascade. To develop the cascade process, a direct ...
