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.
