Abstract

This personal account summarizes our recent work regarding the addition of allenyl cuprates to aldehydes. An intertwined experimental and theoretical study enables highlighting of the crucial role of Li+ as a structuring agent in the different intermediates and transition states involved, and thus on the diastereochemical outcome of the reaction.
