A novel approach to oxoisoaporphine alkaloids via regioselective metalation of alkoxy isoquinolines

Melzer, Benedikt C.,Bracher, Franz

supporting information, p. 1564 - 1571 (2017/08/14)

Oxoisoaporphine alkaloids are conveniently prepared via direct ring metalation of alkoxy-substituted isoquinolines at C-1, followed by reaction with iodine. Subsequent Suzuki cross-coupling of the resulting 1-iodoisoquinolines to methyl 2-(isoquinolin-1-y
