A facile and efficient synthetic strategy to construct polysubstituted 2-aminopyrroles/pyridines was developed via chemoselective Michael addition/intramolecular cyclization reaction under very mild conditions. It suggested that the chemoselectivity of the process could be controlled by the leaving ability of the halides.

On the basis of a designated in situ oxidation tactic, the synthesis of 3-halochromones has been realized for the first time by using simple KX (X = Br, I) salts as halogen sources. Instead of the free radical process, the control experiments indicate that the reported reactions proceed through a halogenium intermediate. Compared to the known synthetic methods relying on molecular halogen, haloid acid or N-halosuccinimide as the halogen source, the present method is attractive due to its higher atom economy and being more friendly to the operator, thus providing a practical complimentary approach to the preparation of useful halochromone compounds.

Abstract The synthesis and antimycobacterial activity of formononetin analogues is hereby reported. Formononetin and its analogue 11E showed 88% and 95% growth inhibition, respectively, against the H37Rv strain of Mycobacterium tuberculosis. Pharmacophore modeling studies indicated that the presence of a hydroxyl group in formononetin and its analogues, is crucial for maintaining activity.
