The reaction of 1-iodo-3-bromopropene derivatives (1) with lithium enolates of N,N-dialkylcarboxamides followed by treatment of the allylation product (2) with two equiv of t-BuLi cleanly provides cyclopentenones in high yields, while the corresponding cycliacylation reaction of 6-iodo-5-hexenamides provides cyclohexenones.
