Summary: | A Friedel-Crafts–type ring-opening/intramolecular Michael addition cascade reaction of (E)-4-(3-(dimethylamino)phenyl)but-3-en-2-one with dimethyl 2-phenylcyclopropane-1,1-dicarbo-xylate catalyzed by Yb(OTf)3 has produced a new compound, dimethyl 7-(dimethylamino)-3,4-dihydro-1-(2-oxopropyl)-4-phenylnaphthalene-2,2(1H)-dicarboxylate. This reaction provided diastereoslective trans tetralin (7:3 dr) on the cyclohexyl ring. The structure of the newly synthesized compound was determined using 1H-, 13C-NMR, IR and mass spectral data. |
