1,3-Dipolar cycloaddition of 3-oxidopyridinium betaine to activated olefins on solid-phase leads to resin-bound 8-azabicyclo[3.2.1]octenones which undergo further transformations such as 1,4-addition of nucleophiles. Cleavage of benzyl linker is achieved
Aryne cycloaddition with 3-oxidopyridinium species

The [3 + 2] cycloaddition of arynes with 3-oxidopyridinium species is examined using the Kobayashi benzyne precursor. The reaction affords a bicyclo[3.2.1] skeleton under mild conditions. A [7 + 2] cycloaddition mode with a subsequent pyridine ring-opening event has also been observed.
Structure of the Calystegines: New alkaloids of the nortropane family
Ducrot,Lallemand
, p. 3879 - 3882 (2007/10/02)
Three new alkaloids have been isolated from Calystegia sepium; their structures have been established from their 1H and 13C N.M.R. spectra, and confirmed by the synthesis of model compounds.
1,3-Dipolar Character of Six-membered Aromatic Rings. Part 56. The Cycloadditions of Acetylenes and 3-Oxidopyridinium Betaines
Ishag, Christina Y.,Fisher, Keith J.,Ibrahim, Badr Eldin,Iskander, George M.,Katritzky, Alan R.
, p. 917 - 920 (2007/10/02)
Cycloaddition of dimethyl acetylenedicarboxylate with a variety of 1-substituted 3-oxidopyridinium betaines yields novel furan cycloadducts.Methyl phenylpropiolate reacts similarly with the activated 1--3-oxidopyridinium betai
