PHENYLIODONIUM DERIVATIVES OF N-HETEROCYCLES AND CH-ACIDS, THEIR SYNTHESIS, AND THEIR USE IN THE CHEMISTRY OF HETEROCYCLES
Keywords:
betaines, β-dicarbonyl compounds, ylides, indole, iodosylbenzene, malononitrile, pyrazolidinedione, pyrrole, sulfones, uracil, cyclopentadienesAbstract
The reactions of iodosylbenzene with CH-acids, including β-dicarbonyl and N-heterocyclic compounds in the presence of alkali, which lead to the aryliodonium ylides (betaines) used in the synthesis of new derivatives of heterocycles, are examined. Both β-dicarbonyl compounds and the anions of various heterocyclic compounds (pyrrole, indole, pyrazolidinedione, hydroxypyrones, hydroxypyridones, oxo-and dioxopyrimidines) and β-keto sulfones, β-disulfones, cyclopentadienes, and malononitrile enter into the reaction.
