Abstract
1,2-Disubstituted indolines have been prepared in good yields by a Zn-mediated organometallic Mannich reaction, followed by an intramolecular Buchwald-Hartwig reaction. The reactions are easy to set up and compatible with a broad range of simple or commercially available reagents. The method was further extended to the preparation of a 1,2,3-trisubstituted indolines.
