99–100% lethality in H. contortus. Of the 22 acrylonitrile analogues investigated, the most active were 2-cyano-3-[1-(3-dimethylaminopropyl)-2-methyl-1H-indol-3-yl]-N-hexylacrylamide (13a), 2-cyano-3-[1(2-dimethylaminoethyl)-2-methyl-1H-indol-3-yl]-N-hexylacrylamide (13b), 2-cyano-3-4-[3-(dimethylamino)propoxy]phenyl}-N-octylacrylamide (21), and 2-cyano-3-1-[3-(dimethylamino)propyl]-1H-pyrrol-2-yl}-N-octylacrylamide

Rapid access to the quinolin-2-(1H)-one scaffold is afforded by a sequential 4 component Ugi–Knoevenagel condensation of an aminophenylketone, an aromatic aldehyde possessing electron donating moieties, cyanoacetic acid and an aliphatic isocyanide, in moderate to good yields (49–71%). Interestingly, when the reaction is performed using aromatic aldehydes bearing electron withdrawing moieties or isocyanides
