A common feature in indole‐ and benzofuran‐derived natural products is a quaternary stereocenter in the 3‐position of the heterocycle. The catalyst (−)‐ 1 promotes the asymmetric synthesis of such compounds 3 (with up to 99 % ee ) through the rearrangement of O ‐acylated benzofuranones (X=O) and oxindoles (X=NR 2 ) 2 .
