title: An efficient one-pot synthesis of heterocycle-fused 1,2,3-triazole derivatives as anti-cancer agents.
abstract: A series of heterocycle-fused 1,2,3-triazoles were easily prepared by the 1,3-dipolar cycloaddition of heterocyclic ketene aminals or N,O-acetals with sodium azide and polyhalo isophthalonitriles in a one-pot reaction at room temperature without a catalyst and evaluated in vitro against a panel of human tumour cell lines. 1,3-Oxazoheterocycle fused 1,2,3-triazoles were more potent against the tumour cell lines Skov-3, HL-60, A431, A549 and HepG-2 than 1,3-diazoheterocycle fused 1,2,3-triazoles. 4-Methoxyphenyl substituted 1,3-oxazoheterocycle fused 1,2,3-triazole 6j was found to be the most potent derivative with IC(50) values lower than 1.9 microg/mL against A431 and K562 human tumour cell lines.
