TL;DR: In this article, the authors used hydrolytic kinetic resolution (HKR) of functionalised epoxides using (salen)Co(OAc) complexes to obtain enantiomerically enriched epoxide and diols which have been transformed into important insect sex pheromones.

TL;DR: Eight new tigliane- and daphnane-type diterpenes were found in Pimelea elongata, and the structures and relative configurations of the new compounds were determined by 1D and 2D NMR spectroscopic studies in combination with MS analyses.

TL;DR: An efficient route detailing the construction of the central core of pierisformaside C, the first grayanane-type diterpene to possess three central double bonds, is reported.

TL;DR: The Caribbean sponges of the genus Plakortis, P. halichondrioides, and P. simplex have provided a series of biologically active furanolactones-the plakortones A-D from the former sponge and B-F from the latter, which settle constitutional and stereochemical features in this group of secondary metabolites.

TL;DR: Capillary gas chromatography, mass spectrometry, and high resolution 13C NMR spectroscopy confirmed 1 as either 84a or 84b and 2 as either 15a or 15b and the novelty of these structures and their relative stereochemistry is briefly related to polyketide assembly.
