Covering: 1973 to 2013. The biological activities of tigliane, lathyrane, ingenane, casbane, jatropholane and premyrsinane diterpenoids which contain the gem-dimethylcyclopropyl unit are described. Particular attention is given to their anti-viral, anti-microbial and cytotoxic activities. In the main text there are 132 references. The electronic supplementary information contains tables listing 424 of these diterpenoids, their occurrence and biological activity together with the references.

“…In 2011, four new premyrsinane‐type diterpenes ( 56 – 59 , Figure 8) were isolated from the methanol extract of the whole, undried plant of Euphorbia falcata , together with two new and one known cyclomyrsinane‐type diterpenes ( 53 – 55 ) 67,68. The compounds are di‐, tetra‐, penta‐, hexa‐ and heptaesters of diterpene polyols, esterified with acetic, benzoic, propanoic, isobutanoic, n ‐hexanoic, 2‐methylbutanoic and benzoic acids.…”

A nanotemplate surface that functions as a regular array of traps for molecules such as naphthalocyanine (see picture) is provided by a nanomesh of hexagonal BN on Rh(111), which has now been identified as a single, complete monolayer. The 2‐nm‐sized pores form at regions where the layer binds strongly to the underlying metal, while the regular network of mesh wires corresponds to regions where the layer is not bonded to the substrate.

“…The 1D NMR spectroscopic data of 5 were analogous to those of diterpene B (Sulyok et al, 2011;Vasas et al, 2012;Appendino et al, 1999;Ahmad and Jassbi, 1998); however, the oxygenated methine at C-7 in diterpene B was replaced by a methylene in 5, which was proved by the HMBC correlations from H 3 -17 to C-5 (d C 117.3, d), C-6 (d C 146.7, s), and C-7 (d C 36.9, t). The structure of 5 was further supported by the HMBC and 1 H-1 H COSY spectra (see Fig.…”
