## Abstract The use of binaphthophosphepine **1a** as a catalyst for the [3+2] cyclisation between allenoates or 2‐butynoates andimines was investigated. The effects of the imine protecting group on both the catalytic activity and enantioselectivity were determined by comparing the behaviour of __N
