Article abstract of DOI:10.1016/0040-4039(92)88045-7

Allenyl enolates generated from 1,6 additions of organocopper reagents to 3-ethynyl-2-cycloalkenones act as ambident α,γ-nucleophiles. The γ:α ratio of products is a function of carbon hybridization, steric environment, and cycloalkenone ring size; typically, γ-products predominate.
