Homoallyllic Nitrone Isomerization: Convenient Enantioselective Synthesis of Homoallylic Nitrones and Homoallylic Hydroxylamines
摘要:
An alpha-regioselective synthesis of homoallylic nitrones from aldehydes is reported on the basis of [3,3]-sigmatropic rearrangement. The products are obtained in up to 99% enantioselectivity and up to 80% yield under environmentally benign and mild reaction conditions.
