Abstract

Ten new constitutionally unsymmetrical azaspiran systems were synthesized upon condensation of Na-derivatives of 2,3-dihydro-1H-benzimidazol-2-one and 2,3-dihydro-1H-benzimidazol-2-thione, respectively, with 1,1-bis(bromomethyl)-and 1,1-bis(iodomethyl)- and ditosylate of 1,1-bis(hydroxymethyl) cycloalkanes.
