Efficient Pd-catalyzed cyclization of homoallylated β-bromo-vinylalcohols via a domino process to carbocycle derivatives in presence of different bases is reported. An unexpected and novel palladium-mediated Heck-type intramolecular oxidative cyclization of 1-bromohexa-1-ene-5-yn-3-ol derivatives is also described.
