Abstract

This short review summarizes decarboxylative reactions of malonic acid half thio/oxyester mediated by metal complexes and organocatalysts. These biomimetic reactions are inspired by similar reactions catalyzed by polyketide synthase. While they have been known for several decades, this is the first review of these reactions.
