, p. 679 - 694 (2007/10/03)
The reaction between β-substituted methylidenemalononitriles and the ylide from (-)-8-phenylmenthyl α-pyridiniumacetate, which affords activated cyclopropanes bearing two cyano groups and one carboxylic ester group, was examined. The trans isomer was obta

, p. 9847 - 9851 (2007/10/03)
The reaction of various mono-substituted methylidenemalononitriles with (-)-8-phenylmenthyl α-pyridiniumacetate in the presence of base afforded the corresponding dicyanocyclopropane compounds with exclusive trans-selectivity and good diastereoselectivity
