Stoichiometric KOtBu in THF enables an efficient transition metal-free approach for the generation of N-unsubstituted imines from azides. Trapping with allyl nucleophile provides N-unsubstituted homoallylic amines. Further, an enantio- and diastereoselective synthesis of homoallylic amines from benzyl azide has also been exemplified.
