experimental part, p. 3905 - 3908 (2011/08/09)
The enantioselective tandem Michael addition-cyclization reaction between 3-methyl-2-pyrazolin-5-one and benzylidenemalononitriles was studied with modularly designed organocatalysts (MDOs) to yield 6-amino-5- cyanodihydropyrano[2,3-c]pyrazoles in high yi

supporting information; experimental part, p. 2252 - 2255 (2009/07/26)
The first enantioselective synthesis of biologically active 6-amino-5-cyanodihydropyrano[2,3-c]pyrazoles has been achieved through a cinchona alkaloid-catalyzed tandem Michael addition and Thorpe-Ziegler type reaction between 2-pyrazolin-5-ones and benzyl
