The preparation of 16 derivatives of 3,5,8-trioxo-4-azatricyclo- [5.2.2.0(2.6)]undec-1-yl acetate and 8 derivatives of 1-isobutoxy-4-azatricyclo[5.2.2.0(2.6)]undecane-3,5,8-trione was described. Substituents to the imide N-atom were alkyl-(aryl)piperazine fragments with an alkyl linker being propyl or butyl group. Selected newly obtained compounds were evaluated in vitro against anti-HIV-1 acti...
Iron-catalyzed carbonylation reactions are highly desirable in our sustainability-advocating chemical community because of its low cost, abundance, and potential for distinct complementary reactivity patterns. Meanwhile, alkyl bromides as well nucleophilic amides indoles considered to be particularly challenge substrates reactions. Herein, we report an iron-catalyzed carbonylative coupling unac...
A series of chiral aromatic imides and diimides were synthesized and their electrochemical, absorption, fluorescent, and chiroptical properties were examined for their potential application as molecular chiroptical switches. These compounds exhibit strong UV–vis absorptions, and can be electrochemically reduced to radical anions that absorb in the near infrared (NIR) region. Further reduction t...
We have designed and synthesized a new donor/acceptor-type tetracene derivative by the introduction of dicarboxylic imide and disulfide groups as electron-withdrawing and -donating units, respectively. The prepared compounds, tetracene dicarboxylic imide (TI) and its disulfide (TIDS) have high chemical and electrochemical stability as well as long-wavelength absorptions of up to 886 nm in the t...
