8-Methoxyisoquinoline derivatives through ortho-selective metalation of 2-(3-methoxyphenyl)ethylamine
摘要:
Butyllithium in diethyl ether smoothly metalates 2-m-anisyl-N-pivaloylethylamine at the aromatic position flanked by the two substituents. Subsequent reaction with N,N-dimethylformamide followed by acid catalyzed cyclization and reduction gives 8-methoxy-1,2,3,4-tetrahydroisoquinoline.
The invention relates to novel tetrahydroisoquinoline derivatives and their use as active ingredients in the preparation of pharmaceutical compositions. The invention also concerns related aspects including pharmaceutical compositions containing one or more of those compounds and their use as medicaments for the treatment or prevention of protozoal infections, such as especially malaria.
