Baylis-Hillman acetates were synthesized from substituted 2-chloronicotinaldehydes and were conveniently transformed into multisubstituted quinolines and cyclopenta[g]quinolines on reaction with nitroethane or ethyl cyanoacetate via a successive S(N)2'-S(N)Ar elimination strategy. Thus, synthesized quinolines were evaluated for antimicrobial activity and(More)
New Baylis-Hillman adducts are synthesized based on substituted 2-chloronicotinaldehydes and screened for their in vitro anti-malarial activity against chloroquine sensitive and chloroquine resistant Plasmodium falciparum. Out of the six new compounds synthesized and screened, 2b, 2c and 2d compounds showed substantial anti-malarial activity.
2-Chloro-5-methylpyridine-3-olefin derivatives (3a-e) have been synthesized from 2-chloro-5-methylnicotinaldehyde (1) and studied their photochemical E (trans)-->Z (cis) isomerization upon direct irradiation and triplet sensitized excitation for the first time. The triplet sensitized excitations of the compounds yielded high Z (4a-e) isomer composition,(More)
