The present invention is directed towards the synthesis of novel and new chloropyridine skeleton based compounds and these are Bayllis Hillman adducts having a remarkable in vitro anti-malarial activity. These compounds have been found to possess anti-malarial activity against chloroquine sensitive and chloroquine resistant
Plasmodium falciparum
. The anti-malarial compounds of the present invention inhibit the mature schizonts in vitro.
were synthesized using pyridinecarboxaldehyde derivatives and cyclic enones. The Baylis–Hillman reaction was examined by employing various organic tertiary bases and solvents. It was observed that DBU in MeOH as well as imidazole and N-methylimidazole in aqueous MeOH are very effective. These pyridinecarboxaldehydes were reactive and efficient towards the Baylis–Hillman reaction and the resulting adducts
