Covering: 2015 up to the end of 2020 Even in the golden age of NMR, the number of natural
products being incorrectly assigned is becoming larger every day. The use of quantum NMR …

Covering: 2020 This review covers the literature published in 2020 for marine natural
products (MNPs), with 757 citations (747 for the period January to December 2020) referring …

In the early 2000s, the first articles regarding the calculation of NMR parameters for natural
products appeared in the literature. Since then, modelling 1H and 13C chemical shifts and …

The chemical investigation of the South China Sea soft coral Sinularia humilis has resulted
in the isolation of a library of diverse diterpenoids, including four new cembranoids, namely …

A novel norditerpenoid, sinusiaetone A (1), featuring an uncommon bicyclo [11.3. 0]
hexadecane carbon skeleton, and four polyoxygenated cembranoids (2–5) were isolated …

Marine organisms often produce a variety of metabolites with unique structures and diverse
biological activities that enable them to survive and struggle in the extremely challenging …

Soft corals are well-known as excellent sources of marine-derived natural products. Among
them, members of the genera Sarcophyton, Sinularia, and Lobophytum are especially …

Cembrane diterpenoids (cembranoids), characterized by a 14-membered carbon ring and
wide variety of functional groups, found in marine and terrestrial organisms. Many studies …

NMR data prediction is increasingly important in structure elucidation. The impact of force
field selection was assessed, along with geometry and energy cutoffs. Based on the …

Structure elucidation is a stage of paramount importance in the discovery of novel
