Alternate Method for the Dimerization of 2-Benzylidene inden-1-one Derivatives: Synthesis of 1,3-Diaryl-1,3,3a,8a-tetrahydro-8H-spiro[cyclopenta[a]indene-2,2'-indene]-1',8(3'H)-diones
Journal Title: Cumhuriyet Science journal - Year 2017, Vol 38, Issue 3
Abstract
In the present study, a series of 1,3-diaryl-1,3,3a,8a-tetrahydro-8H-spiro[cyclopenta[a]indene-2,2'-indene]-1',8(3'H)-dione derivatives (4a-h) were synthesized by KOt-Bu catalyzed dimerization of 2-benzylidene inden-1-one derivatives. The structures of obtained novel spiro-dimeric compounds were characterized using the spectroscopic methods (1H, 13C, 2D NMR and IR).
