Abstract

A simple protocol for the C1 arylation of tetrahydroisoquinolines with aryl Grignard reagents via diethyl azodicarboxylate (DEAD) mediated oxidative C–H activation under metal-free conditions has been developed. The target compounds, including some naturally occurring alkaloids, were obtained in moderate to good yields.
