chalcones with an electron rich group or sterically large groups such as naphthyl on the carbonyl side tend to activate PPARγ. The absence of any strict structural or electronic requirements suggests that the flexibility of the PPARγ ligand binding pocket may allow binding of diverse chalcones with some preference for a slightly larger electron-rich group on the carbonyl side. We predict that further structure-activity

A variety of fluoro-substituted 2,4,6-triarylpyridines have been prepared via the reaction of 4-picolinium 4-chlorophenacyl methylide, with a series of fluorinated α,β-unsaturated ketones in the presence of ammonium acetate in acetic acid.
Regioselective [3+2] cycloaddition of chalcones with a sugar azide: easy access to 1-(5-deoxy-d-xylofuranos-5-yl)-4,5-disubstituted-1H-1,2,3-triazoles

[3+2] Cycloaddition of 5-azido-5-deoxy-1,2-O-isopropylidene-alpha-D-xylofuranose with 1,3-diphenylprop-3-enones, followed by oxidation of the intermediate triazolines in a tandem manner, led to the regioselective formation of 4-benzoyl-1-(5-deoxy-1,2-O-isopropylidene-alpha-D-xylofuranos-5-yl)-5-phenyl-1H-1,2,3-triazoles in moderate to good yields.
