Abstract
Aminoquinoline derivatives are known for their superlative efficacy in the treatment of many diseases. An efficient synthesis of Betti bases via a one-pot three-component reaction of 2-bromophenol, substituted aldehydes, and 3-aminoquinoline in polar media using DBU as a catalyst is reported considering its atom economy, short reaction time, good yield, and easy workup. The obtained compounds were well characterized by IR, NMR, and mass spectra and were screened in vitro for their antidiabetic activity against acarbose as reference drug. Compounds having chloro substituents were found to exhibit significant activity while those with NO2, Br, and F substituents showed moderate activity. The lowest antidiabetic properties were found in the compounds with electron-donating groups (Me).
