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).
Özet
Bu çalışmada, bir seri 1,3-Diaril-l,3,3a,8a-tetrahidro-8H-spiro[siklopenta[a]inden-2,2'-inden]-1',8(3'H)-dion türevi (4a-h), 2-benziliden inden-1-on türevlerinin KOt-Bu katalizli dimerleşmesi yolu ile sentezlendi. Elde edilen yeni spiro-dimerik bileşiklerin yapıları spektroskopik yöntemlerle (1H, 13C, 2D NMR ve IR) karakterize edildi.
