Abstract
Morita-Baylis-Hillman adducts, prepared from 2-nitrobenzaldehyde precursors and either methyl acrylate or methyl vinyl ketone, have been used as critical synthons in the preparation of α-[(alkylamino)methyl]cinnamate esters and their but-3-en-2-one analogs, cinnamate ester-azidothymidine (AZT) conjugates, 2-quinolone and quinoline derivatives. Computer docking studies have been conducted to explore the potential of the cinnamate ester-AZT conjugates as potential dual-action HIV-1 integrase-reverse transcriptase (IN-RT) inhibitors. The results further demonstrate the applicability of Morita-Baylis-Hillman methodology in the construction of complex drug-like scaffolds.
