The trichloroacetamidine intermediates, generated by addition of benzylamine derivatives to trichloro-acetonitrile, react with the Knoevenagel condensation product of ninhydrin and malononitrile to afford trichloromethylated [3.3.3]propellanes, in good yields. When benzylamine was used, a plane-symmetri-call cal spiro-compound was obtained. (C) 2014 Elsevier Ltd. All rights reserved.
