Michael reactions withtrans-3-isopropenyl-2-phenylthiocyclopentan-1-one andtrans-3-isopropenyl-2-phenylsulfonylcyclopentan-1-one

摘要

The condensation of methyl acrylate with the title β-ketosulfide and β-ketosulfone was studied. The primary adduct of β-ketosulfone with acrolein readily undergoes intramolecular aldolization to give bicyclo3.2.1octane derivatives. The molecular structure of one of them was elucidated by X-ray analys
