Thionium ions, generated by the addition of thiols to N-benzylglyoxamides, undergo a dearomatizing spirocyclization. The alkyl or arylsultanyl group introduced during the thionium ion cyclization can act as a synthetic handle and a stereochemical control element during modifications of the azaspirocyclic frameworks (R(F) = CH(2)CH(2)C(8)F(17)).

reagents and catalysts. The functionalization of C-Hbonds β to the nitrogen of aliphatic amines to form prevalent 1,2-amino functionalized structures is particularly challenging because the C-H bond β to nitrogen is stronger than the C-H bond α to nitrogen, and the nitrogen in the amine or its derivatives usually directs a catalyst to react at more distal γ- and δ-C-H bonds to form 5- or 6-membered metallacyclic
