Treatment of secondary aliphatic 2-bromoallylamines with an excess of an organolithiumcompound led to saturated amines in which the organic group of the organolithiumcompound is incorporated at the alpha carbon. On the other hand, the successive reaction of the former amines with BuLi and t-BuLi between -80 degrees C and rt gave 1,3-diamines or hexahydropyrimidines depending on the reaction time
