Synthesis of Thiourea and Sulfonylurea Derivatives of Chalcones and Flavones and their Biological Evaluation

Chalcone and flavone derivatives based on thiourea and sulfonylurea (6, 7a and 7b, 13a and 13b) were synthesized and confirmed by spectral data. All the target compounds were evaluated for in vivo antihyperglycemic activity in sucrose loaded model (SLM) a

Nickel catalysed carbonylative Sonogashira reaction for the synthesis of diarylalkynones and 2-substituted flavones

The nickel catalyzed, palladium/phosphine free carbonylative Sonogashira reaction of terminal alkynes with substituted aryl and heteroaryl iodides is described. This protocol provides mild and robust conditions to synthesize a variety of substituted aryl α,β-alkynyl ketones and flavones in good to excellent isolated yields. This methodology tolerates several functional groups such as electron donating (methyl, isopropyl, tert-butyl, methoxy) as well as electron withdrawing (trifluoromethyl, nitro, esters, nitrile) groups on the terminal alkynes and iodides.
