Indium triflate catalyzes efficiently the one-pot three-component
condensation of aldehydes, amines, and allyltributylstannane to
afford the corresponding products of homoallylic amines in excellent
yields at room temperature. All reactions were carried out using
the catalyst in 10 mol%. This methodology was successfully
applied to a variety of aldehydes and amines.
aldehydes - amines - allyltributylstannane - indium triflate - homoallylic amines
