Recent Advances of Cinnamic Acids in Organic Synthesis

Abstract The great success of cinnamic acids was rooted in their multiple functional groups. Herein, reactions triggered by the radical addition, electrophilic addition, Michael addition and reactions of acids were thoroughly discussed and summarized. Multi‐component reactions, rearrangements, stereoselective synthesis, coupling, additions will be depicted in detail. This review focused on advances of cinnamic acids in the last decade (2010–2020). We hope this review will be good for a better understanding of these reagents and future research.
