A Claisen-Schimidt condensation of 2-hydroxyacetophenones 1a-f with an aldehyde 2 yielded a series of compounds 3a-f. Compounds 3a-f were transformed into series of substituted chromones 4a-f, pyrazolines 5a-f and aurones 6a-f on treatment with DMSO/ I₂, NH₂NH₂ / EtOH and Hg(OAc)₂ / pyridine respectively. All these novel compounds were characterized by spectral techniques. All the compounds were screened for their antibacterial potential.
