    Description / Table of Contents: Potentielle H1-Antihistaminica: Synthese von 4-[(2,3-Dihydro-2-oxo-1H-benzimidazol-1-yl)alkoxycarbonyl]-1-(diphenylmethyl)piperazinen durch selektive Phasen-Transfer-katalysierte Monoalkoxycarbonylierung von α,ω-DichloralkanenDie Synthese einer Reihe von neuen 4-[(2,3-Dihydro-2-oxo-1H-benzimidazol-1-yl)alkoxycarbonyl]-1-(diphenylmethyl)piperazinen 2 durch Phasen-Transfer-katalysierte Monoalkoxycarbonylierung von α,ω-Dichloralkanen wird beschrieben. Die Piperazine 2 ähneln Oxatomid1) (1) und sind potentielle H1-Antihistaminica. Ferner wurde eine Untersuchung zur regioselektiven Synthese von substituierten 1,3-Dihydro-1-isopropenyl-2H-benzimidazol-2-onen (5) durchgeführt.
    Notes: The synthesis of a series of new 4-[(2,3-Dihydro-2-oxo-1H-benzimidazol-1-yl)alkoxycarbonyl]-1-(diphenylmethyl)piperazines 2 by phase-transfer catalysed monoalkoxycarbonylation of α,ω-dichloroalkanes is described. Compounds 2 are related to oxatomide1) (1) and are potential histamine-H1 antagonists. A study on the regioselective preparation of substituted 1,3-dihydro-1-isopropenyl-2H-benzimidazol-2-ones (5) was also carried out.
