Abstractmagnified imageA series of substituted 1,8‐naphthyridine‐3‐carboxylates were synthesized for the first time from the Baylis–Hillman adducts obtained from 2‐chloronicotinaldehyde derivatives. Three methods were adopted to synthesize 1,8‐naphthyridine‐3‐carboxylates, of which the azide‐reduction route (Scheme 5) gave the best yields compared to the other attempted methods (Schemes 2 and 3).

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.
