Diterpenoids: Natural Distribution, Semisynthesis at Room Temperature and Pharmacological Aspects‐A Decade Update
Sasadhar Majhi
Abstract
Abstract Diterpenoids are a wide and structurally diverse class of natural products and secondary metabolites obtained from four isoprene units joined in a head‐tail fashion. It has been extensively investigated that a semisynthesis is an essential tool for enhancing the biological activity of starting natural products. Different diterpenoids have been employed as starting materials for the synthesis of bioactive semisynthetic derivatives at room temperature in this review. Energy plays a profound role in chemical transformations. However, according to the sixth principle of green chemistry, the most successful route to save energy is to develop strategies/protocols that are able enough to perform the reactions at ambient temperature. This review is aimed to offer an overview of natural distributions of diterpenoids, design, and semisynthesis of diterpenoids at room temperature, and highlights biological activities of semisynthetic derivatives for the first time from 2010–2019.
