title: Phosphine-catalyzed [4+1] annulation of 2-tosylaminochalcones with allenoates: synthesis of trans-2,3-disubstitued indolines.
abstract: 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.
