RESUMEN
Determination of the absolute configuration is considered one of the most complicated works in the natural products study. Mosher's method provides a practical solution for the stereochemistry determination of natural products by means of NMR spectroscopy. This article, which reviews the classic application of Mosher's method, is one of the series of historical stories on natural product chemistry published in this journal.
RESUMEN
Ocean is a unique and excellent resource that provides a diverse array of intriguing natural products. Marine natural products have demonstrated significant and extremely potent biological activities and have captured the attention of natural products chemists in the past few decades. It is increasingly recognized that a wealth of fascinating natural products and novel chemical entities will play a dominant role in the discovery of useful leads for the development of pharmaceutical agents and provide useful probes to lead to breakthroughs in a variety of life-science fields. This article focused on the research progress of chemistry of marine natural products in recent five years.
