An efficient catalytic four-component reaction of carbonyl compounds (or acetals/ketals), benzyl chloroformate (CbzCl), 1,1,1,3,3,3-hexamethyldisilazane (HMDS), and allyltrimethylsilane has been successfully developed to produce Cbz-protected homoallylic amines in the presence of 5 mol % of iron(II) sulfate heptahydrate (FeSO4·7H2O), an inexpensive and environmentally friendly catalyst, at room temperature
