Enantioselective photocyclisation reactions of 2-aryloxycyclohex-2-enones mediated by a chiral copper-bisoxazoline complex

Edtmüller, Verena,P?thig, Alexander,Bach, Thorsten

, p. 5038 - 5047 (2017/07/27)

The photocyclisation of the title compounds leads upon direct irradiation at λ = 366 nm in dichloromethane solution to racemic cis-2,3,4a,9b-tetrahydro-1H-dibenzofuran-4-ones (nine examples, 37–74% yield). Since it was found that the substrates show a sig
