of isoprene (20 mol%) in THF at room temperature. By reacting this organolithium with carbonyl electrophiles 2-(hydroxyalkyl)imidazoles 3 were obtained, in good yields. As a result of the reaction of the mentioned lithium intermediate with imines 4, the corresponding 2-(aminoalkyl)imidazoles 5 were isolated in excellent yields.
