title: Unprecedented rearrangement of a 4-alkoxy-5-bromoalk-2-en-1-ol to a cyclopentenone via an iso-nazarov cyclization process.
abstract: We report the structure determination of the product 9 of the rearrangement of the allylic alcohol 3 under very mild conditions, probably promoted by an acidic substance, and propose a reasonable mechanism for its formation.
