A simple and facile synthesis of homoallylic amines using silica supported sodium hydrogen sulfate

Silica supported sodium hydrogen sulphate (NaHSO4·SiO2) catalyzes efficiently the three-component reactions of aldehydes, amines and allyltributylstannane to form the corresponding homoallylic amines at room temperature. The catalyst is inexpensive and eco-friendly and works under heterogeneous conditions.
