Potential cancer chemopreventive in vitro activities of monomeric xanthone derivatives from the marine algicolous fungus Monodictys putredinis.
TLDR
Investigation of the fungal strain Monodictys putredinis isolated from the inner tissue of a marine green alga led to the isolation of four new monomeric xanthones and a benzophenone, which were examined for their cancer chemopreventive potential.

Metal-Free sp(2)-C-H Borylation as a Common Reactivity Pattern of Frustrated 2-Aminophenylboranes.
TLDR
It is demonstrated that simple 2-aminopyridinium salts efficiently catalyze the C-H borylation of hetarenes with catecholborane and that this reaction is presumably mediated by a borenium species isoelectronic to2-aminophenylboranes.

Ring-opening of Epoxides Mediated by Frustrated Lewis Pairs.
TLDR
Based on computational and kinetic studies, the mechanism of these reactions was found to proceed via activation of the epoxide by the Lewis acidic borane moiety followed by nucleophilic attack of the phosphine of a second FLP molecule.
