A general and practical method of synthesis of α,β-unsaturated sulphonates (25 examples) by the Wittig-Hornerreaction is described. Reactions with the salts 2 and carbonyl compounds are not very stereoselective. On the contrary, reactions with esters 1 gave high yields of (E)-α,β-unsaturated sulphonic esters.
This invention relates to certain N-heteroaryl compounds that are generally useful as medicaments, more specifically as medicaments for animals. The medicament can preferably be used for the treatment of helminth infections and the treatment of parasitosis, such as caused by helminth infections. This invention also relates to uses of the compounds to make medicaments and treatments comprising the administration of the compounds to animals in need of the treatments. This invention also relates to novel N-heteroaryl compounds and the preparation of said compounds. Moreover this invention relates to pharmaceutical compositions and kits comprising the compounds.
