A new method that allows the complete control of the regioselectivity of the hydrobromination reaction of alkenes is described. Herein, we report a radical procedure with TMSBr and oxygen as common reagents, where the formation of the anti-Markovnikov product occurs in the presence of parts per million amounts of the Cu(I) species and the formation of the Markovnikov product occurs in the presence of 30 mol % iron(II) bromide. Density functional theory calculations combined with Fukui's radical susceptibilities support the obtained results.

We herein describe a Ni-catalyzed multicomponent coupling reaction of alkyl halides, isocyanides, and H2O to access alkyl amides. Bench-stable NiCl2(dppp) is competent to initiate this transformation under mild reaction conditions, thus allowing easy operation and adding practical value. Substrate scope studies revealed a broad functional group tolerance and generality of primary and secondary alkyl halides in this protocol. A plausible catalytic cycle via a SET process is proposed based on preliminary experiments and previous literature.

A series of novel antifungal carboline derivatives was designed and synthesized, which showed broad-spectrum antifungal activity. Particularly, compound C38 showed comparable in vitro antifungal activity to fluconazole without toxicity to human embryonic lung cells. It also exhibited good fungicidal activity against both fluconazole-sensitive and -resistant Candida albicans cells and had potent inhibition activity against Candida albicans biofilm formation and hyphal growth. Moreover, C38 showed good synergistic antifungal activity in combination with fluconazole (FLC) against FLC-resistant Candida species. Preliminary mechanism studies revealed that C38 might act by inhibiting the synthesis of fungal cell wall.
