Abstract
A chiral phosphine catalyzes the addition of a carbon nucleophile to the γ position of an electron-poor allene (amide-, ester-, or phosphonate-substituted), in preference to isomerization to a 1,3-diene, in good ee and yield. This strategy provides an attractive method for the catalytic asymmetric γ functionalization of carbonyl (and related) compounds.
