Abstract
Cyclopentanone reacts with arylidenemalononitriles 1a–c to give dihydro-4,6-indenedicarbonitriles 5a–c. Similarly, the diethyl dihydro-4,6-indenedicarboxylate derivative 6 is formed when treating ethyl α-cyanocinnamate (1d) with cyclopentanone. Cyclopenta[b]pyrans 5a–c are obtained from the reaction of diarylidene derivatives of cyclopentanone with malononitrile.
