C-Centred opticallyactive allylsilanes react with carbonylcompounds in presence of Lewis acids to give the corresponding homoallyl alcohols with ee varying from 21 to 56 %. The role of the Lewis acid is crucial for a correct development of the reaction; different procedures are tested and the results compared.
