A series of novel indan-2-one and dibenzylidenepiperidin-4-one compounds were synthesized and screened for anticancer activities. The compounds are symmetrical and they have conjugated double bonds. They closely resemble the curcumin analogs which are found to possess anticancer properties. The structure of the compounds was confirmed by single crystal study and wherever the compound is a powder, the structures were confirmed by spectral data (IR, NMR, and Mass).
Synthesis of new spirooxindole derivatives through 1,3-dipolar cycloaddition of azomethine ylides and their antitubercular activity
Non-stabilized azomethine ylides, generated in situ from isatin derivatives and c-proline, have been reacted with (E,E)-1,3-bis(arylidene)indan-2-ones as dipolarophiles in a 1,3-dipolar cycloaddition reaction. Novel functionalized dispiroheterocyclic compounds were obtained with low diastereoselectivity and the regiochemical outcome of the cycloaddition reaction was confirmed by single crystal X-ray analysis. The compounds were investigated by in vitro screening against Mycobacterium tuberculosis (MIC) using the agar dilution method and displayed good activities. (C) 2015 Elsevier Ltd. All rights reserved.
