asymmetric Claisenrearrangement of allylvinylethers has been effected with a chiral organoaluminumreagent, (R)-1 or (S)-1 as an example of the enantioselective activation of ether substrates. This method provides a facile asymmetric synthesis of various acylsilanes and acylgermanes with high optical purity. Among various trialkylsilyl substituents of chiral organoaluminumreagent 1, use of the more
