Abstract
Silacyclopentanes have been prepared from vinyl(homoallyl)silanes or vinyl(liomopropargyl)silanes and organolithium reagents by a tandem intermolecular-intramolecular sequence involving a 5-exo cyclisation process. The unexpected stereochemical outcome of the sequence involving a 5-exo-dig cyclisation is rationalised. (C) 2003 Elsevier Ltd. All rights reserved.
