2-Cyclopenten-1-one → 5,6-Diphenyl-2,3,3a,4,7,7a-hexahydro-1H-inden-1-one

Participants

Reaction Steps

A mixture of 2,3-diphenyl-1,3-butadiene (2.772 g, 13.44 mmol) and cyclopent-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 5,6-diphenyl-2,3,3a,4,7,7a-hexahydro-inden-1-one.
