Witryna22 lis 2024 · Let’s first quickly summarize what Bond-Line (Zig-zag) structures are: 1) There is a carbon at each junction (corner) and periphery. 2) Each carbon has enough hydrogens to have 4 bonds (unless there is a formal charge) So, essentially in bond-line structures, we don’t show the hydrogens and carbons. All the heteroatoms (any … WitrynaChemical investigation of the fungus Trichoderma sp., isolated from the Caribbean sponge Agelas dispar led to four novel sorbicillinoid polyketide derivatives (1–4) with an unprecedented tricyclic ring system. The structures of all compounds, including the absolute configuration, were determined by interpretation of their spectroscopic data …
