Abstract

Cascade reactions (also represented as domino reactions) realize the step-economical direct construction of natural product core structures. The use of atom-economical elementary reactions in cascade processes can minimize waste production and avoid prefunctionalization of the substrates. Palladium catalysis, which promotes a variety of atom-economical elementary reactions, has long been used as a powerful approach to the direct formation of complex heterocycles. In this short review, palladium-catalyzed cascade reactions for the construction of core structures of natural products reported in the last decade­ are highlighted.1 Introduction2 Reactions Terminated with Heteronucleophiles2.1 Termination with Nitrogen Nucleophiles2.2 Termination with Oxygen Nucleophiles3 Reactions Terminated with Carbon Functional Groups3.1 Termination with Carbon Nucleophiles3.2 Termination with Heck-Type Reactions4 Conclusion
