A method of preparing 5-aryl-1,2-pentamethyleneimidazoles from O-methylcaprolactim and α-amino-acetophenone hydrochlorides is described. It is shown that 1,2-tri-, -tetra-, and -pentamethyleneimidazoles and phenacyl bromide give the corresponding quaternary imidazolium salts, cyclization of which in the presence of base gives the previously unknown 5, 6, 7, 8-tetrahydro-2a,4a-diazacyclopenta[c, d]azulenes (IVa-i). 1997 Plenum Publishing Corporation.
