Mild, Fast, and Easy to Conduct MoCl5-Mediated Dehydrogenative Coupling Reactions in Flow

A convenient and straightforward approach to performing oxidative coupling reactions in flow is presented. A collection of electron-rich benzene derivatives was subjected to this protocol, and the distinct utility of molybdenum pentachloride (MoCl5) is established. Using this unexplored protocol, biphenyls could be obtained in 21-91% isolated yield. This simple protocol opens a new chapter in reagent-mediated dehydrogenative coupling reactions, and yields are compared to classical approaches.

Efficient halogenation synthesis method of aryl halide

The invention discloses an efficient halogenation synthesis method of aryl halide. The method comprises the following step: in the presence of a catalyst (sulfoxide or oxynitride), a halogenation reagent and a solvent, carrying out a halogenation reaction on an aromatic ring compound to obtain the aryl halide.

Syntheses of the fungal metabolites Boletopsins 7, 11, and 12 from the Papua New Guinea medicinal mushroom Boletopsis sp.

Boletopsins 7 (1), 11 (2), and 12 (3) are p-terphenyl dibenzofuran compounds, isolated from the Papua New Guinean medicinal mushroom Boletopsis sp. The first syntheses of these fungal metabolites are reported, allowing for an investigation of their antibiotic activity. The key steps include sequential Suzuki-Miyaura couplings to rapidly form the p-terphenyl backbone and an Ullmann ether synthesis on a formate ester to create the dibenzofuran moiety. Biological evaluation of the synthetic compounds and intermediates against a panel of bacterial nosocomial pathogens was performed.
