Hydrocinnamic Acids: Application and Strategy of Synthesis

Abstract

This review summarizes all the main approaches to the synthesis of hydrocinnamic acids based on the construction of the side chain with a carboxy moiety around the aromatic ring. Numerous methods for the synthesis of hydrocinnamic acids by constructive or destructive routes, such as reductive or oxidative reactions, rearrangements, catalytic reactions, or electrochemical conversion, are considered and presented in a rational system.
