, p. 12653 - 12656 (2015)
Phosphine-catalyzed [4+1] annulation of 2-tosylaminochalcones with allenoates has been achieved, giving trans-2,3-disubstitued indolines as major diastereoisomers in moderate to good yields.

A practical method for the synthesis of N-(2-carbonylaryl) benzenesulfonamides via an iron-catalyzed electrophilic amination of sodium sulfinates with anthranils is described. This redox-neutral transformation has high atom efficiency and is achieved under simple and mild reaction conditions. A wide range of anthranils and sodium sulfinates were compatible in this transformation. Moreover, the synthetic potential of this methodology was further demonstrated by the synthesis of various useful N-heterocycles and derivatives.
Cascade Skeletal Rearrangement of Gold Carbene Intermediates: Synthesis of Medium-Sized Pyrimidine-Fused Benzolactones
