aliphatic amines add to acyclic and cyclic α,β-unsaturated thioamides yielding β-amino-functionalized derivatives. In the case of cyclic acceptors, the formation of both kinetic and thermodynamically controlled products is observed. Tailoring of cis or trans products is thus possible. A mechanism for the addition to cyclic acceptors is proposed and evidence presented to support it. Ease of addition is studied
