Design, synthesis and characterization of novel fluorinated styryl chromones

225-228(E)-3-(3-(Trifluoromethyl)-5-nitrophenyl)acrylic acid 1 when treated with substituted 2-hydroxyacetophenones 2 in dry pyridine and POCl3 affords compound 3 which when reacted with pyridine/KOH by B. V. transformation gives 4. Compound 4 on refluxing with acetic acid in HCl gives 5. The structures of all synthesized compounds have been confirmed by spectroscopic techniques

Synthesis of novel fluorine containing imidazolyl aurones and benzofurans

1243-1247Imidazolyl aldehyde 1 on reaction with substituted 2-hydroxyacetophenone 2 gives chalcone 3, which on treatment with mercuric acetate in dry pyridine gives compound 4 and when treated with dry acetone in K2CO3 with 4-bromophenacylbromide gives compound 5. The structures of all the synthesized compounds have been confirmed by spectroscopic techniques

Synthesis, characterization and antibacterial screening of fluorinated benzofuran containing heterocycles

504-5102-(4-Fluorophenyl)-5-phenylbenzofuran-3-carboxylic acid 1 when treated with substituted 2-hydroxyacetophenones 2 in dry pyridine and POCl3 affords compound 3 which when reacted with pyridine/KOH by B. V. transformation gives 4. Compound 4 on refluxing with different reagents Ac2O in presence of sodium acetate, acetic acid in HCl, and hydrazinehydrate in alcohol gives 5, 6 and 7 respectively. The structures of all synthesized compounds have been confirmed by spectroscopic techniques. All the synthesized compounds have been screened for their antibacterial activity
