Treatment of aryl 2-iodophenyl ketones with TMS2NH in the presence of Sc(OTf)3 at warming conditions, followed by the reaction with styrenes and NIS gave N-(1-aryl-2-iodoethyl) aryl 2-iodophenyl ketimines. Further treatment of N-(1-aryl-2-iodoethyl) aryl 2-iodophenyl ketimines with tBuOK in the presence of 1,10-phenanthroline at 120 °C generated 1,3-diarylisoquinolines in moderate yields through SET from tBuOK onto the iodophenyl group to form aryl radicals, their 6-endo-trig cyclization onto the vinyl groups, and aromatization of the cyclized intermediates. The present method is a novel approach for the preparation of the isoquinoline core via two steps from aryl 2-iodophenyl ketones.
