2-Iodoisatogens: Versatile Intermediates for the Synthesis of Nitrogen Heterocycles
摘要:
A Cu-promoted cyclization of 2-nitrophenyl iodoacetylenes provides a direct route to a range of 2-iodoisatogens. These compounds represent useful intermediates for the late-stage elaboration of the C-I bond to furnish isatins and a range of alternative heterocyclic products.

We have developed a new strategy for preparing 2-substituted indolone N-oxides (isatogens) by substitution reactions with aryl- and alkyl-organometallic reagents. This approach allows a range of substituents to be incorporated at a late stage and complements existing methods that necessitate their early stage incorporation during substrate preparation. Further chemistry has been found to take place
