Alkyne [3 + 2] cycloadditions of iodosydnones toward functionalized 1,3,5-trisubstituted pyrazoles.

Duncan L Browne1, John B Taylor, Andrew Plant, Joseph P A Harrity.   

Abstract

The cycloaddition of 4-iodosydnones with terminal alkynes proceeds with excellent regiocontrol to provide 5-iodo pyrazoles. These products participate smoothly in subsequent C-C and C-heteroatom bond forming processes.
