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.
