General description

Photocycloaddition of 2-cyclohexenones to 1,2-bis(trimethyl-siloxy)cyclobutene has been studied. It undergoes Aldol condensation reaction with carbonyl compounds. It reacts with Br2 to give cyclobutanedione.

Application

1,2-Bis(trimethylsiloxy)cyclobutene has been used in the synthesis of:
  • functionalized decalins, required for the total synthesis of various sesquiterpenes and diterpenes
  • angularly substituted bicyclo[4.3.0]nona-2,5-diones and bicyclo-[4.4.0]deca-2,5-diones
  • 3-methoxyestra-1,3,5,8,14-pentaen-17-one
