Coupling–Isomerization Synthesis of Chalcones

Chemistry – A European Journal, 2006
AbstractThe Sonogashira coupling of electron‐deficient (hetero)aryl halides 1 and (hetero)aryl or alkenyl 1‐propargyl alcohols 2 does not terminate at the stage of the expected internal propargyl alcohols, but rather gives rise to the formation of α,β‐unsaturated ketones 3 with a variety of acceptor substituents.

Expression of chalcone synthase and chalcone isomerase proteins in Arabidopsis seedlings

Plant Molecular Biology, 1997
Antibodies have been developed against the first two enzymes of flavonoid biosynthesis in Arabidopsis thaliana. Chalcone synthase (CHS) and chalcone isomerase (CHI) were overexpressed and purified from Escherichia coli as fusion proteins with glutathione S-transferase from Schistosoma japonicum.

Chalcones XVI: infrared spectral studies of phenanthryl chalcones

Monatshefte f�r Chemie, 1977
IR absorption spectra of ten phenanthryl chalcones have been studied with a view to see the effect on stretching frequencies of α, β-unsaturated carbonyl group when conjugated to the phenanthryl nucleus.
