The present invention relates to the uses of sesquiterpene lactone compounds and their derivatives in preparing drugs. It belongs to the field of drug technology, specifically relates to the uses of the compounds of Formula (I) in preparing the drugs, especially the uses in preparing the drugs to treat rheumatoid arthritis and treat cancers through inhibiting cancer stem cells.
Organocopper(I) reagents, RCu, are both more stable and more reactive when prepared in dimethyl sulfide instead of ether or tetrahydrofuran. A wide range of Li reagents has been investigated with good results, as has a selection of Grignard reagents. Excellent yields of products are observed with typical substrates such as α,β-unsaturated ketones and acid chlorides.

Tri-n-butylphosphine-catalyzed acylation of mixedn-alkyl phenylzincs with aromatic acyl halides in THF is efficient in selective transfer of n-alkyl groups to produce n-alkylaryl ketones in good yields. This route provides an atom economic organocatalyzed alternative to transition metal-catalyzed acylation of di-n-alkylzincs.
