title: Behaviour of 2-substituted 1,3-indandiones towards aldimines.
abstract: Treatment of 2-cyano-1,3-indandione (1) with aldimines gave the expected Mannich bases (2-4), while the arylidenes (7,8) were obtained when 2-ethoxycarbonyl-1,3-indandione (5) was subjected to react with aldimines. On the other hand, treatment of 2-acetyl-1,3-indandione (9) with aldimines gave compounds (11,12,14). The reaction of 2-phenyl-1,3-indandione (15) with aldimines gave the arylamino and the ethylene diamino derivatives (17, 18). Pictet Spengler reaction of 19b gave the spiro compound (21).
