A series of beta-formyl-BODIPYs 2 were synthesized in high yields from tetramethyl-BODIPYs 1 via the Vilsmeier-Haack reaction and were further functionalized using a Knoevenagel condensation to generate novel BODIPYs 3 and 4.

This study demonstrates that several natural coumarins (one linear pyranocoumarin and one angular pyranocoumarin in particular) exhibit strong antifungal activities. These results call for further studies, where these coumarins can be examined as potential lead compounds for developing novel antifungal agents. © 2016 Society of Chemical Industry.

An efficient and practical Rh­(III)-catalyzed redox-neutral [4 + 1] annulation of N-phenoxy amides with α,α-difluoromethylene alkynes has been realized to give direct access to the Z-configured monofluoroalkenyl dihydrobenzo­[d]­isoxazole framework with broad substrate compatibility and good functional group tolerance, which was further enhanced by the late-stage C–H modification of complex bioactive compounds. Subsequent density functional theory calculations revealed that the stereoselective β–F elimination involving an allene species played a decisive role in determining the reaction outcome and such Z-selectivity.
