- Design, synthesis, and structure-activity relationship of 7-propanamide benzoxaboroles as potent anticancer agents
-
Benzoxaboroles, as a novel class of bioactive molecules with unique physicochemical properties, have been shown to possess excellent antimicrobial activities with tavaborole approved in 2014 as an antifungal drug. Although urgently needed, the investigation of benzoxaboroles as anticancer agents has been lacking so far. In this study, we report the design, synthesis, and anticancer structure-activity relationship of a series of 7-propanamide benzoxaboroles. Compounds 103 and 115 showed potent activity against ovarian cancer cells with IC50 values of 33 and 21 nM, respectively. Apoptosis was induced by these compounds and colony formation was effectively inhibited. Furthermore, they also showed excellent efficacy in ovarian tumor xenograft mouse model.

- A Tethered Tolane: Twisting the Excited State
-
The synthesis of a doubly bridged tolane is reported. The target is obtained in a five-step synthesis, starting from commercially available 2-amino-meta-xylene by a combination of a Sandmeyer reaction, radical bromination, and Stille-type coupling, followed by double ring closing. The doubly tethered tolane is crystalline; the two phenyl rings are highly twisted with respect to each other both in solution and in the solid state. Optical spectroscopy and quantum chemical calculations show that the doubly bridged tolane is twisted not only in the ground state, but also in the excited state, leading to emission from the twisted state in solution and in the solid state. Strong phosphorescence is observed at cryogenic temperatures.

- Iron-Catalyzed Hydrosilylation of Aldehydes and Ketones under Solvent-Free Conditions
-
Exposure of aldehyde or ketone to 1 mol % BIAN-Fe(C7H8) complex in the presence of diphenyl silane affords the corresponding protected alcohol in excellent yields, under mild reaction conditions. Aldehydes and ketones are reduced cleanly in the presence of a broad range of functional groups under solvent-free conditions.

- Convenient and versatile synthesis of formyl-substituted benzoxaboroles
-
Despite of the medicinal significance of benzoxaboroles, with the newly discovered clinical compound AN2690 as an example, the synthetic method for rapid diversification of this novel scaffold is lacking. To this end, a versatile and scalable synthesis of formyl-substituted benzoxaboroles is described here. A key step is the mono-oxidation of the two hydroxyls in compound 4 by taking advantage of the stable oxaborole ring in non-coordinating solvents, which was devised based on the study of the intramolecular coordination and exchange properties.
