                                The first examples of permanganate promoted oxidative cyclisations of 1,6-dienes are described, providing exclusively cis-2,6-bis-hydroxyalkyl-tetrahydropyrans. In addition, good levels of asymmetric induction have been attained using dienoyl sultam substrates. (C) 2004 Elsevier Ltd. All rights reserved.
