An effective indium-catalyzed oxidative cross-dehydrogenative coupling of electronically varied chromenes with 1,3-dicarbonyl compounds and aryl rings has been established. Both the C-H alkylation and arylation proceed smoothly at room temperature to afford diverse α-substituted chromene compounds in up to 91% yields. Besides these two types of C-H components, simple ketones like cyclohexanones also prove to be well tolerated. This journal is © The Royal Society of Chemistry 2015.

An activated manganese dioxide (MnO2)-BF3·OEt2 oxidation system was developed to efficiently mediate the intramolecular as well as intermolecular biaryl coupling. The oxidative coupling proceeds smoothly at ambient temperature to deliver the corresponding five- to eight-membered tricyclic products in good to excellent yields. The employment of the combination of MnO2 and BF3·OEt2 is attractive on the basis of economical and environmental issues. © the Partner Organisations 2014.

Three new xanthone derivatives, including two first reported containing sulfur as natural products: sydoxanthone A (1) and sydoxanthone B (2), and 13-O-acetylsydowinin B (3) were isolated from an endophytic fungus Aspergillus sydowii, occurring in the livewort Scapania ciliata S. Lac, together with seven known biosynthetically related compounds (4-10). Their structures were established primarily by NMR, UV and MS data. In vitro suppression test on the Con A- and LPS-induced proliferations of mouse splenic lymphocytes showed that compounds 7 and 8 displayed moderate immunosuppressive activities. © 2013 Phytochemical Society of Europe.
