Abstract
1-Benzyt-1,4-dihydronicotinamide (1) and KCN reacted with 2-(o-bromomethyl) -benzylidene-1,3-indandione (2) to give 7, 12-dihydro-1-oxoindeno[3,2-c][2] benzooxepine (3) a nd 1'-cyano-3'-hydro-2, 2'-spirobi[2H-indene]-1,3-dione (4), respectively, and the selectivity of O-alkylation and C-alkylation is discussed.
