title: Direct FeX3-based stereocontrolled access to (Z)-3-alkenyl-oxindoles from allenols.
abstract: Iron trihalides (FeCl(3) and FeBr(3)) smoothly promote the halogenation/rearrangement of 2-indolinone-tethered allenols to efficiently afford 3-halodienyl-oxindoles with good yield and total selectivity. Also, 2-halo-1,3-dienes are synthetically interesting building blocks for the preparation of functionalized 3-alkenyl-oxindoles through a Suzuki-Miyaura reaction.
