  Remote asymmetric induction based on carbonyl-ene reactions with bishomoallylic silyl ethers: dramatic changeover of regioselectivity by the remarkable siloxy effect

  摘要：

  A new approach to remote asymmetric induction is described for not only a 1,4- but also a 1,5-relationship, which is based on the carbonyl-ene reactions with chiral bishomoallylic silyl ethers. Silyl ethers, rather than alkyl ethers, exhibit beta-regiospecificity. Remarkably high levels of remote asymmetric induction can then be established with chiral bishomoallylic ethers to provide eventually a simple and efficient method for asymmetric induction.
