Abstract
The synthesis of complex natural products must be realized with high economy and efficiency, contributing largely to sustainable development in synthetic organic chemistry. The new strategies should adopt protecting‐group‐free approaches enabling step‐economy and thereby enhancing efficiency. Various approaches based on chiral pool, auxiliary‐based methods, cascade, biomimetic, enzymatic and photocatalytic used in total synthesis of natural products and following the PGF‐criteria over the last two years (2018–2019) have been reviewed here. These should guide sustainable synthesis of natural products in the future.
