AbstractThe construction of oxepin and dihydrooxepin containing natural products represents a challenging task in total synthesis. In the last decades, a variety of synthetic methods have been reported for the installation of these structural motifs. Herein, we provide an overview of synthetic methods and strategies to construct these motifs in the context of natural product synthesis and highlight the key steps of each example.1 Introduction2 Oxepin Natural Products3 Dihydrooxepin Natural Products3 Brønsted or Lewis acid Catalyzed Cyclization3.2 Radical Cyclization3.3 Substitution and Addition Cyclization3.4 Sigmatropic Rearrangement3.5 Oxidative Methods3.6 Transition Metal Catalyzed Cyclization4 Summary

Here, we have summarized more than 30 representative natural product syntheses published in 2015 to 2020 that employ one or more Horner-Wadsworth-Emmons (HWE) reactions. We comprehensively describe the applied phosphonate reagents, HWE reaction conditions and key steps of the total synthetic approaches. Our comprehensive review will support future synthetic approaches and serve as guideline to find the best HWE conditions for the most complicated natural products known

Divergent synthesis is a powerful but yet underdeveloped method to address the usual drawbacks of poor supply and confined diversity in the total synthesis of natural products. Herein, we describe the rational design behind the selection and the synthesis of a divergency scaffold for sesquiterpenoid lactones synthesis, as a case study, which provides access to a rich collection of carbocycles in different oxidation states within 8,12-sesquiterpenoids through simple, scalable transformations.

In this Account, we describe our studies on the total synthesis of several natural products using intramolecular Nozaki–Hiyama–Takai–Kishi (NHTK) reactions. In each synthesis, an NHTK reaction is used to efficiently construct a medium-sized ring. These examples demonstrate the utility of the intramolecular NHTK reaction in natural product synthesis.1 Introduction2 Total Synthesis of (+)-Pestalotiopsin A3 Total Synthesis of (+)-Cytosporolide A4 Total Synthesis of (+)-Vibsanin A5 Total Syntheses of (+)-Aquatolide and Related Humulanolides6 Conclusion
