Abstract:
The synthesis of a library of new biaryl-based carbazoles via bidentate directing group-assisted C-H functionalization and preliminary screening of the anticancer properties of biaryl-based carbazoles is reported. While various classes of modified carbazoles are known for their applications in materials and medicinal chemistry, to our knowledge, the biological activities of designed biaryl-based carbazoles have been rarely known. Given the prominence of carbazoles in research in medicinal chemistry, we envisioned the scope for new scaffolds of carbazole-based biaryl structures. We screened the synthesized biaryl-based carbazoles for their anticancer properties against various cancer cell lines such as HeLa (cervical cancer), HCT116 (colon cancer), MDA-MB-231 and MDA-MB-468 (breast cancer). In addition, the hits were also tested in the human embryonic kidney cell line HEK293T to assess their impact on the viability of normal human cells in the presence of these compounds. In this preliminary study, we identified some of the biaryl-based carbazoles as lead compounds with anticancer activities.

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
