histones, which are controlled by histone lysine demethylases (KDMs). Series of benzo[b]tellurophene and benzo[b]selenophene compounds were designed and synthesized and they were evaluated for histone H3 lysine 9 demethylase (KDM4) inhibitory activity. Among the carbamates, alcohol and aromatic derivatives, tert-butyl benzo[b]tellurophen-2-ylmethylcarbamate (compound 1c) revealed KDM4 specific inhibitory
Reaction of acetophenone hydrazones with TeCl4 in the presence of DBU in CH2Cl2 at rt gave vinyl ditellurides and tellurides, whereas 2,5-diaryltellurophenes were obtained in refluxing DMF. Interestingly, when 1,2-diphenylethanone hydrazone was used as the substrate, 3-phenylbenzotellurophene was obtained in 45% yield. The reaction would proceed through telluroketone intermediates.

2-Substituted and unsubstituted benzo[b]tellurophenes (3Aa-e) were synthesized in one-pot from o-bromoethynylbenzenes (2) via three steps in good yields. Similarly, benzo[b]-selenophenes (3Ba-e) and -thiophenes (3Ca-e) were also obtained.

A simple and cost-effective method for the preparation of benzo[b]tellurophenes has been developed: overnight heating of o-haloarylalkynes with Te-NaOH-DMSO triad without the need for dry and inert atmosphere provides the corresponding benzo[b]tellurophenes.
