Versuchsvorschrift
A mixture of 2,3-diphenyl-1,3-butadiene (2.772 g, 13.44 mmol) and cyclohex-2-enone (1 eq.) was refluxed in toluene (26 mL) for 48 h. The reaction mixture was then concentrated and purified on SiO2 (20% ethyl acetate/hexane) to yield 6,7-diphenyl-3,4,4a,5,8,8a-hexahydro-2H-naphthalen-1-one.
