The reaction of 1-iodo-3-bromopropene derivatives (l\_) with lithium enolates of N,fl-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-5hexenamid
