Photochemical reactions of cyclopropyl ketones by electron transfer
No full textSchmoldt P, Kirschberg T, Fagnoni M, Mattay J. Photochemical reactions of cyclopropyl ketones by electron transfer. JOURNAL OF INFORMATION RECORDING. 1998;24(3-4):249-252.Photoinduced electron transfer (PET) from triethylamine (TEA) to cyclopropyl ketones initiated a cyclopropylcarbinyl-homoallyl rearrangement. Attack of the so formed homoallyl radicals on a terminally unsaturated side chain gave various bicyclic products the structure of which depends on the position and length of that side chain
Reductive cyclization of alpha-cyclopropylketones with alkynyl- and aryl-tethered substituents

Tetrahedron. 1998;54(23):6427-6444.Photoinduced electron transfer (PET) reactions of alpha-cyclopropyl-substituted ketones and triethylamine (TEA) were used to initiate the cyclopropylcarbinyl-homoallyl rearrangement. The intramolecular cyclization reaction onto triple bonds was performed yielding bicyclic and spirocyclic compounds. Furthermore, in some preliminary studies it was shown that even intramolecular aromatic substitutions are feasible. (C) 1998 Elsevier Science Ltd. All rights reserved
