Transition-metal templates offer an opportunity to provide new dimensions for selectivity in organic reactions. In examining the question of regioselectivity of allylic we were intrigued by the possibility of enhanced selectivity for attack at the more substituted end of a n-allyl metal intermediate (eq 1).
