A Traceless Directing Group for CH Borylation1. Issue 49 (12th November 2013) - Preshlock, Sean M.
Abstract Not a trace: Borylation of the nitrogen in nitrogen heterocycles or anilines provides a traceless directing group for subsequent catalytic CH borylation. Selectivities that previously required Boc protection can be achieved; furthermore, the NBpin directing group can be installed and removed in situ, and product yields are substantially higher. Boc=tert‐butoxycarbonyl, pin=pinacolato.
