of primary and secondary E-allylic amines by reduction of 1-azadiene intermediates is described. β-Enamino phosphonium salts are suitable starting materials to prepare secondary allylic amines. Two methods are reported for the obtention of primary allylic amines from 4-amino-1-aza-1,3-dienes. Method A leads to the desired compounds by straight reduction with AlH3 or DIBALH; method B is a stepwise procedure

The 3-amino-2-alkinimines 1 are photochemically reactives. Their irradiation in solution (tetrahydrofuran, methanol, diethyl ether, toluene) produces substitutedquinolines 2 in good to acceptable yields. A six electon electrocyclic process is proposed.
