RT Journal Article T1 A novel modification of the Ritter reaction: stereoselective synthesis of bridgehead-fused Δ2-norbornanethiazolines from thiocamphor and thiofenchone A1 García Martínez, Antonio A1 Teso Vilar, Enrique A1 Moreno Jiménez, Florencio A1 Álvarez García, Ana María AB An easy two-step route for the stereoselective synthesis of novel bridgehead-fused norbornanethiazolines from readily available natural camphor and fenchone is described. The key step of the synthetic route is the highly stereoselective trapping of 1-(trifluoromethylsulfonylthio)-2-norbornyl cations by nitriles followed by intramolecular cyclization, which constitutes a new modification of the Ritter reaction PB Elsevier SN 0957-4166 YR 2006 FD 2006-11-17 LK https://hdl.handle.net/20.500.14352/52834 UL https://hdl.handle.net/20.500.14352/52834 LA eng NO Received 18 September 2006, Accepted 2 November 2006, Available online 1 December 2006.
