Abstract

On treatment with t-BuLi and DMPU, 1-naphthamides bearing N-allyl or N- prenyl substituents cyclise to give a mixture of products from which seven- membered lactams can be isolated in up to 73% yield - the first example of an organolithium-C=C cyclisation leading to a seven-membered ring.
