Abstract
Functionalized allylsilanes 1-4 undergo palladium(II) catalyzed ring closur e to afford 4- and/or 5-substituted 2-vinyltetrahydrofurans (5-8) under mil d conditions. The catalytic reactions proceed through (eta(3)-allyl)palladi um intermediates formed by palladadesilylation of the allylsilane substrate s. (C) 2000 Elsevier Science Ltd. All rights reserved.
