Asymmetric synthesis of β-amino cyclic ethers via the intramolecular reaction of γ-alkoxyallylstannane with chiral imine
摘要:
The Lewis acid mediated cyclization of gamma-oxygen substituted allylic stannane 1, having a chiral imine group at the terminus of the carbon chain, afforded trans beta-amino cyclic ether 2 with very high to good diastereoselectivities in high chemical yields.
