Oxidative free-radical cyclizations of unsaturated 2-cyclohexenones 9a, 9b, 17, and 24 with Mn(OAc)3 afford unsaturated α′-keto radicals such as 10 that cyclize to afford bicyclic products. The major process with 2-cyclohexenone 27 is conjugate addition of acetate to form β-acetoxy α-keto radical 37. Unsaturatedaldehydes 45, 57a, and 57b are oxidized to radicals that cyclize to give cyclopentane- and
A pro-fragrance composition includes a cucurbituril in complex with a fragrance molecule and use of the compositions in counteracting malodour. The cucurbituril is present as a mixture, wherein the mixture includes at least two different cucurbiturils selected from CB[5], CB[6], CB[7] and CB[8]. The complexed fragrance molecule is released when the composition is exposed to a stimulus. Also provides methods for the preparation of pro-fragrance complexes of cucurbiturils and fragrance molecules.
